I have a problem with JSF2, and RichFaces ajax, Popup I have two, one in which I display a table with data and another that appears when I want to insert a new data by clicking on a button ... but I have a problem . In fact, before the data is inserted into the table I would like to check that this is not already present, if it is I have to display an error message, otherwise close the Popup used to enter the data and display the table which is located in Popup previous year, as I proceed? you can give me an example :)

I have a very simple Oracle Apex app. I created a button on the home page. I also created a second page using the "Form" template, and the source for this form is a table in the local database.
I set the button to open the form, and I passed the value of the primary key of this form (it's a column called ID) from the home page to the form page, as this screenshot of the button's behavior shows (3 is the page number of the form, P3_ID is the page item in the form associated with the primary column "ID", and 1 is the value that I passed for P3_ID):
The table that the form references is empty, i.e. there is no row with ID equal to 1. Meaning I want to pass the value of 1 to this form so that it automatically create a row with ID of 1 after the user fills out the rest of the form. Here is the form page:
Now the error. When I run the app and press the button, I get this error:
The error says it's from the process called "Initialize form Warcraft Particulars". I searched everywhere and I couldn't find a process by that name anywhere in the app. What am I doing wrong?
Pre-rendering process (in a form) will try to execute query and fetch a row whose ID = 1; as it doesn't exist, Apex raises the no_data_found error. That's why you got it (the error).
Moreover, you're doing it wrong - don't pass ID you'd want to create, fill it in form's process (or use a database trigger which will put a sequence number into the ID column, or use an identity column if your Oracle database supports it (12c onward)).
Furthermore, I'd suggest a slightly different approach: don't create a form that's alone in the Universe. Approach that lets you both view existing data, update (or delete) it and insert new rows is to use a Wizard and choose a report with a form. Exact naming is different from one Apex version to another; for example, current apex.oracle.com Apex version is 22.2 and it offers "Interactive report", while the 1st Wizard page lets you choose whether you want (or not) to include a form page (you'd say "Yes").
Anyway: once you find the correct option, choose it and wizard will then create an interactive report page you'd use to
view current data
it has an edit icon at the beginning of each row which - when pressed - navigates to the form page where you can edit values or delete entire row
create new row (by pressing the "Create" button)
and a form page which does what I described a moment ago.
I have created a page based on "Form & Report" template. So there is the Report page on which there is the create button. That create button leads to the form page which contains.
It is pretty simple. I don't know if there is a cache memory not emptying itself or if there is a setting that I have not properly set.
When I want to create a new database record, Oracle Apex behaves as if I asked it to update a record (though it still presents me with empty text fields).
Below the image of what's happening.
Create button of the Report
Buttons for edit are shown when I click the create button
Those edit buttons are shown instead of the buttons below => This means that the Apex software is behaving like I asked to edit a record not to insert a record.
Why is this happening?
You need to take a look at your create button. Is it passing a value to the form? If so, you probably don't want that. Is it clearing the cache of the form? If not, you probably want to clear it.
Also, on the form page take a look at your processes.. specifically the Automated Row Fetch (ARF) process.. what's the primary key that this process is using?
Also, take a look at the conditions for each button on your form. For the delete/save buttons you likely want a condition type of "value of item / column in expression 1 Is NOT NULL".
For your create button you would want the opposite.. "value of item /... IS NULL".
In both cases for the expression 1 you'd want to use the item that your ARF is leveraging.
#Bloomberg58 if you used the wizard that should not have anyway try to validate the create button in report page and the server-side validation of create and save button in form page
I have a blank page with a static content region (Template = Form Region). I select a project via a select list (there is only one project, so it automatically selects it). I then have a key popup lov (a popup lov that displays the description not the returned number value) from which I select a person to be in this project. I am trying to get the form to display the person I selected and saved previously when the form launches for the first time (since the project is chosen due to there being one). This works when you refresh the page, but it doesn't work if you log out and log back into the form. I tried using the default value with a sql query. I tried using a dynamic action that fires when the project changes; but neither approaches work. I fiddled with all the settings, but couldn't get anything to work. Does anyone know how to accomplish this in Oracle APEX?
I even added a refresh of the cascading popup lov to the dynamic action. I can see the hidden input item showing my defaulted value, but the popup lov does not display it on screen. Is this an Oracle bug?
Also in Javascript from the console
$s("P51_LINE_MANAGER1", "7104");
sets the hidden value, but doesn't display on screen.
$v("P51_LINE_MANAGER1");
does however return 7104.
My question is very similar to this:
Ajax update doesn't work, when using filter on datatable (JSF, Primefaces).
I have a dataTable with an "Open" button (a commandButton) for each entry/row in the table, on click of which, a dialog will open. I have a form in the dialog that I can update and save. Once I save my changes, I will get back on the dataTable closing the dialog I'm in, updating the results of the save that happened in the dialog on the entry in the table (whose "Open" was clicked to open the dialog).
If I save the results from the dialog and use the update attribute to update the results of the save on the table entry, it works fine. However, if the dataTable was filtered in the first place and then the dialog was opened, then the update does not result in update of the table entry until I actually refresh/reload the page.
The
oncomplete="PF(':parentForm:dataTableVar').filter()"
and
oncomplete="PF(':parentForm:dataTableVar').clearFilters()"
solutions recommended in the other question I referenced don't seem to have any effect in my case.
Any suggestions?
I use JSF v2.1.19 and PrimeFaces v5.1.
You need to mark the list in the attribute filteredValue on dataTable.
Ex: <p:dataTable filteredValue="#{bean.anotherListWithTheSameType}" />
In dialog, it's necessary filteredValue.
From here: http://www.primefaces.org/docs/vdl/4.0/primefaces-p/dataTable.html
It was my mistake to mention the id in place of the widgetVar. This:
oncomplete="PF('myTableWidget').filter()"
would work fine if the dataTable in question looks like:
<p:dataTable id="myTable" widgetVar="myTableWidget"...
I was wrongly trying it this way:
oncomplete="PF('myTable').filter()"
I have a problem regarding modal popup and session.
I have two component name test and test1 respectively.
In test there is a form in view in which i put "Anchor" tag with "modal" class. has also class name "class1".
When i clicked on Anchor tag it call click function(on click "class1") in which i put ajax code for set data using "Session".
$('.test').click(function(){
// Ajax code here for set data using session
});
with above function it also called modal popup. here targer url is seted which is the view of 2nd component which is "test1".
Here in test1 there is a view.html , we are getting session data here and displaying in view.
PROBLEM
Problem is that , here in 2nd component , in view i am getting session data but i need to click on button two time , only after i getting data properly.
When i click on it give me a old session data. and when i click on it second time it will give me a proper data.
What is the solution for above problem. if anyone know please let me know.
Session data is altered only after we click on Anchor tag.
Both thing is done on Anchor click , one is for set data in session and second is for modal popup. in popup i am getting data which set in session.
when is the session data is being altered?
Is it altered by ajax call too?
In this case, javascript, is unsynchronous. It doesn't wait for something to happen in order to fire the next line of code. In that case there are several techniques you may find to do so.
