Oracle APEX - Setting Null Display Value for POPUP LOVs - oracle

I have a few select list boxes on my page and when nothing is selected, I want the value to be shown as Select a Value. So I set Null Display Value property to Select a Value. That works fine for select lists that are using either a shared list or a SQL query as its source, but not for those that use Popup LOV as its source. How can I set null display value for Popup LOVs?

Put "Select a Value" into the Value Placeholder Popup LOV item's property.

getting the selected TEXT in select list and saving it in session

I have a select List which is based on a LOV and the LOV is based on a query, the query is calling a function and gets the LOV. The select list Item itself, stores the ID of the row which is selected but I want the TEXT of the row that is selected to be stored in session so I can access it in my print query in shared components.
i can get the text of selected row of select list by running $("#P952_CODING option:selected").text(); but this just shows the text and when I created a (SET VALUE dynamic action) on the selectlist item and gave it the js expression and as affected element I gave it another Item It didn't work and the new item remained null.what elese can be done?

Hide ssrs textbox based on another textbox value

I am trying to hide a textbox based on another textbox value in a table. In my ssrs 2013 report, I have a column in a table called EmpExist that returns nothing or text like Emp does not exist. On top of the table I have a textbox called Go To when clicked it will take you to another report. I am trying to hide this textbox based on EmpExist column in the table.
I tried the following, setting the visibility of "Go To":
=IIF(ReportItems!EmpExist.Value = "" OR ReportItems!EmpExist.Value IS NOTHING, False, True)
or this:
=IIF(First(Fields!EmpExist.Value, "dataset1") IS NOTHING OR First(Fields!EmpExist.Value, "dataset1") = "", False, True)
The problem is that the Go To textbox will be either visible or hidden regardless of the EmpExist value. If the EmpExist has any value, "Go To" should be hidden, but it is visible. If it does not have any value or nothing, it should display it but it is visible as well.
Thanks.
I ended up using a parameter to check the value of EmpExist and used the expression above (using the parameter instead of the column name) and seems to be working fine. Not sure why I was not able to do it based on textbox value in SSRS 2013

Populating a text box from from the value in a drop down

I'm creating a form in apex where I want to populate a text box with a value which has been selected in a drop down box. This needs to be done using a select statement on the form.
I have tried using a Dynamic action.
If I was using SQL I would pass the value of the id which I have retrieved using a combo box.
SELECT APPLICATION_ID FROM APPLICATIONS WHERE JOBID = :P55_JOBID
this would update my APEX field (P55_APP_ID)
P55_JOBID is the Job ID APEX field.
The Select statement for APP_ID works but I want it to be updated when the Job Dropdown list changes. I've been told to use a Dynamic action but I cant work out how it triggers a refresh of App_ID..
thanks for your help,
mike
Thanks for your help.
You want a dynamic action that is triggered on the Change event of the select list (P55_JOBID). The action of this will be Set Value and the Set Type will be SQL Statement. Add your SQL (SELECT APPLICATION_ID FROM APPLICATIONS WHERE JOBID = :P55_JOBID) here and then under Page Items to Submit include your select list (P55_JOBID).
The Selection Type will be Item(s) and the Item(s) will be your text area (P55_APP_ID).

Displaying all values when Checkbox is unticked Oracle APEX

I created a checkbox in an interactive report for searching a table in APEX. When a option is checked the correct rows are displayed. However when no checkbox option is selected the search function only returns rows with null values. What I want is for all rows to be returned when no option is selected. How can I do this?
This is the code I used to implement my checkbox
WHERE instr(':'||:P20_APP_METHOD||':',application_method)
what about this?
instr(':'||:P20_APP_METHOD||':',application_method) or :P20_APP_METHOD IS NULL

How to Hide/Show of UI component in oracle adf

I am new to oracle adf in my application one of the field is id and it is sequence generated value Whenever I entered remaining values and click on save then only it has to display with sequence generated value before saving it has to be in hide mode. Can any one help me how the approach is.
set visible property for seq field. like below
visible="#{binding.filedName.inputValue != null}"
by default seq field value is null so it will not display. once u click save button, this field value to be set to next seq value so it will display
Just remove this value from UI and do your number generation for this field in model.
You can set the visible attribute of the field in your page to be based on an expression language such as #{viewScope.showfield}, then add a setPropertyListener to your save button that sets the #{viewScope.showfield} to true.
