We have two forms so far, and need to switch from window1 in from1 (which is login screen) to windowX in formX using button (trigger code below):
begin
show_window('windowX');
go_block('some_block_in_formX');
end;
This gives error FRM-41052: Cannot find Window: invalid ID
So question is, should I add formX into show_window parameter in certain way or is there another approach? Thank you.
Please note, that forms are in different files.
that forms are in different files.
If the forms are different files, you need to call the other form using open form/call form/newform - whatever suits your needs.
show_window/go_block sequence can be used only when you're moving to different windows/blocks of the same form - and the error message
error FRM-41052: Cannot find Window: invalid ID
is complaining that it can't go to that Window because it's in a different form.
Each form effectively has a private namespace for all its windows, blocks, items, etc - and your code always runs within the context of a single form.
To solve this, you'll need a form parameter, plus some code in the other form, e.g.:
in formX, add a parameter ACTION
in form1, pass the value 'XYZ' to ACTION
in formX, in the WHEN-NEW-FORM-INSTANCE trigger, check if :PARAMETER.ACTION = 'XYZ', and if so, do your show_window and go_block. Copy the same code to your WHEN-WINDOW-ACTIVATED trigger.
Of course, you'll need to think about the name of the parameter (e.g. ACTION) and value ('XYZ') that will make sense to people maintaining your forms in the future.

I am currently trying to migrate Forms' Applications developped ten years ago to Oracle Apex. For some context, the database in which Forms applications are currently running is the Oracle EE 6i, and will be soon upgraded to the 12.2g, hence the need for migration. The data stored within the tables is to big to migrate (like 4To) so we need an alternative to Forms, but we cannot change the DB, and cannot keep Forms (which is let's be honest, outdated a little). I am currently on Oracle XE for my tests and on Apex 20.2.0.00.20 to start my migration (before upgrading).
The thing is, I have some issues with how Apex and Forms are working differently.
I am really blocking on the following issue since my migration:
In Forms, it was really easy to change the color of a button for exemple by calling a Forms method in a certain way depending on a condition (for exemple a SELECT return). Here, in Apex, I am trying to do the same.
I know that there are ten other ways of doing the same, with JS for exemple which I already succeedly do, but when I tried to create my second appplication I realised that compared to Forms, Apex cannot reference/generalise parts of the code(or applications) for different applications (and certainly not for different workspaces). So Javascript is a good solution but not as efficient as PL/SQL which is easier to generalise and will (in my opinion) use less exchange between the db and the client, since stored on the db.
That is why I decided to rely on PL/SQL Stored Procedure which will be specified in the database and called directly in each application where I need the process/computations.But I cannot find the same as in Forms, with my graphical methods helping me do what I need.
I am open to alternative of PL/SQL package/procedure/function if it can keep the same propreties (generalisation and minimum echange between client and db). These are important point since I have around 200 applications to migrate, starting with what we can call 'brick' which will compose the other simpler applications.
Btw: CSS is an option I studied, like HTML with PL/SQL dynamic content but I read that it was either not simple enough to integrate, or that it could be deprecated, so if it is the solution you are using, I could use a really detailled explaination or an exemple.
To give you an instance:
I click on a button triggering a PL/SQL stored procedure
Procedure checks some conditions in the db (like if a process is currently running)
PL/SQL update a table, change a variable in procedure and returns 'green'
The button becomes green, a message is displayed ('You have permission to do this!')
PS: if there are Apex Method modifying the graphical aspect, could I have a documentation ?
Thank you a lot for helping me resolve this issue, I have been stuck for days...
I tried Javascript bu the generalisation was too much a problem. I tried the HTML injecting but didn't work, I tried updating CSS but was not what I expected. I tried different PL/SQL method but couldn't find a way to connect PL/SQL with Apex/CSS/HTML...
It takes a bit of getting used to how APEX works, but everything can be done and once you get up to speed, you'll find there pretty simple ways to get things done. To achieve what you describe, this is what you'd do.
Create a dynamic action on click of button
Add the following actions to the dynamic actions
an action of type "execute pl/sql". This is your "Procedure checks ...". In this pl/sql code you can set page item values (make sure to reference those in "items to return" so the new values is set in the session. There is no reason to have 2 different pl/sql procedures, you can just put them in 1 block. This procedure would return the "green" - but more about this later.
an action to add a class to the button under certain conditions.
Note that the "green" is not something you should decide. In apex, there are a lot of layout modifier classes pre-defined. In your case, it makes sense to use the "success" modifier (which happens to be green).
To check how you want the button to look, there is a tool called the "button builder", you can use that to see what classes you should add/remove to change the look of the button.
Note that 20.2 is not a recent version. It was released in 2020. Since then 4 more releases have been made available: 21.1,21.2,22.1 and 22.2. It is advised to be on the latest version.
Here is a basic example. I have a page with a select list (P117_SELECTLIST), a hidden item to hold the button status (P117_BUTTON_STATE) and a button (MYBUTTON). The select list has 2 static values:
The dynamic action for serverside code is :
Note the items to submit and return values. P117_SELECTLIST is submitted so the pl/sql process picks that up from the client and P117_BUTTON_STATE is returned to the client so it is available for any future use.
Then I have 4 classes to set the button style. One to add success class, one to remove success class, one to add warning class, one to remove warning class. Below is the first one. The only think different in those 4 actions in the class name and the client condition. It can probably done with javascript directly as well with only 1 action.
I'd strongly suggest to update the db version to a version that supports the latest version of apex. It will save you a lot of development worries. Most people of forums only have the latest version available.
I am facing issues in performing certain actions based on the value in the excel file cell data.
Actions like if value is "NORMAL" then click Container type = Normal (radio button)
Similarly the Unit Container Value
Following is my code:
I am getting this error while performing action .WebElement("Container_Type_Normal").Click
Your error is because you can't start a line with . unless your within a with - and i can't see a with in your function. (i also don't recommend using a with as the can cause needless confusion)
The .webelement object is a catch-all type of object that is the child of other web objects or .page. You need this to be a full and valid path to the object, by this i mean start with browser().page().
You have a couple of options:
You can either make this a full path to your object based on the object repository:
Browser("<<OR Browser name>>").Page("<<OR Page name>>").WebElement("<<Your webelement name>>".click
For this, look at your OR and insert your names.
Or, option 2, you can use descriptive programming:
Browser("CreationTime:=0").Page("index:=0").WebElement("text:=" & fieldValue,"index:=0").click
That will take the browser that was created first (Creation time 0), the only page it has and the first (index 0) web element that contains your text (text is field value).
I'm assuming that you only have one browser, and that the first element that contains the text you want is what you want to click. You may need to add more layers too this or
A good approach is to mirror what is OR or use the object spy to ensure these properties are correct.
I currently have a validation rule that prevents user from making changes to a record when its status is completed. Users are only allowed to make changes if the status is either draft or registered.
AND(
TEXT(Current_Status__c) <> "Draft",
TEXT(Current_Status__c) <> "Registered"
)
There is a new requirement to allow user to update only a specific picklist value field even if the record status is completed. If i remove the validation rule, user will be able to change any fields on the page layout which won't work.
Object setting for the profile is read, create, edit. This object is a child object to Opportunity, OWD is controlled by parent.
Any recommendation on how to solve this issue ?
Thanks in advance.
We can rewrite your rule as ISPICKVAL(Current_Status__c, 'Completed') for example, looks bit cleaner. Your call though, you can keep as is.
So what you'd need is something like ISPICKVAL(Current_Status__c, 'Completed') && !ISCHANGED(Some_Picklist__c). It should let the edit through if you're modifying that picklist.
The problem is it won't check if that's the only change. Usercan cheat, modify 10 fields and they'll "piggyback" and save OK as long as one of them is that picklist.
It's pain to write validation like ISPICKVAL(Current_Status__c, 'Completed') && !ISCHANGED(Some_Picklist__c) && (ISCHANGED(Field1__c) || ISCHANGED(Field2__c) || ISCHANGED(Field3__c)). You'd have to add all editable fields to it, change it every time you make new one. And eventually you'll hit length limits.
I know 3 options for this if it's a concern for you:
Ask a developer to rewrite your logic to Apex trigger, it could then go dynamic through all fields (using "describe" calls to learn field names or stuff like getPopulatedFieldsAsMap.
Another trick is to allow editing completed records only through a quick action, not normal edit page. In that action you could set some hidden checkbox in the field prepopulating step and your validation would let the save through only if that checkbox is set. But then you need to deactivate it somehow anyway or the bypass will get permamently enabled.
If you don't have too many record types on the object a common trick is to change the record type on completion (workflow, process builder etc). And have another page layout with all fields locked down except that special picklist. It works good enough for UI changes but won't protect if you have code and integrations writing to the object too.
In LUIS if you require some parameters for an action, and add a prompt question, if the parameter is missing, it will send the prompt as a dialog option in the answer.
In my case I have 2 required parameters, and if the 2nd one is missing (the quantity) I'd like the prompt asking for clarification to use the value of the other parameter's value.
For example:
query: I would like to buy tickets to toronto.
dialog prompt should
be: How many tickets to toronto?
I tried setting the prompt to something like "how many tickets to {location}" but obviously this doesn't work.
I haven't found any information on this so I think it's just not possible but I'd like confirmation.
I don't think this is possible out of the box. However, I believe it could be done if you start overriding things here and there.
The main problem is that the LuisActionDialog (the dialog that prompts for parameters) is not receiving the original LuisResult model (which makes sense since it's not serializable).
So, I think that to start looking into this, you will have to:
Override the MessageReceived method from the LuisDialog class, in order to create a new dialog that handles the parameters. Please note that overriding the MakeLuisActionDialog method won't be enough, per what I explained before about not receiving the original LuisResult.
Create a new dialog similar to the LuisActionDialog, that will do what the current dialog does but also performs the prompts manipulation that you are looking to have.
LUA novice, experimenting with GUI using iup.GetParam using LUA 5.1.
I have a simple use of iup.GetParam (which works fine with a simple callback function testing for OK & Cancel) and am trying to add some simple data validation for the parameters (e.g. testing a parameter for being alphanumeric), but am unsure of the correct approach.
I've searched the reference manual (and for code examples), but drawn a blank so far.
Using the string validation example, if I want to reject the
character entered by the user and display the old value of the
parameter, do I simply return 0 from the callback function, or, do
I also have to reset the value of the parameter to its previous
value before the return? Or is the right approach something
completely different?
In either case, do I have to refresh / update the GUI display with a
separate iup call, or does GetParam handle that for me?
Whatever combination I try, it doesn't appear to work (the parameter happily displays the non-alphanumerics). Debugging shows the validation test and return working as coded, so the advice I'm seeking is to get confirmation of the right approach. Sharing a simple working example would be great.
simply return 0
No, IUP will do everything for you, in this case
Download the "getparam.wlua" from the examples folder, then add to its callback this:
elseif (param_index == 1) then
return 0
You will notice that the integer value is now read-only.
