How to reload a calling form after closing the called form? [message #251585]

I have FORM_A calling FORM_B: Call_form('FORM_B',...). On form_B I am updating a Record and when I close Form_B and the focus goes back to Form_A, I need to Automatically Reload Form_A to reflect the changes that were made on Form_B.

How can I reload the Calling Form (FORM_A) when I closed the called form (FORM_B)?

EXECUTE_QUERY on the block, perhaps? (following the CALL_FORM command)

Hi Littlefoot,

I am not calling FORM_A from FORM_B. I am currently Only Closing FORM_B and automatically the focus goes back to form A with the OLD data.

Can you tell me how can I know in Form_A that I am back from B and I regained the focus then maybe I can call my WHEN-NEW-FORM-INSTANCE to reload the data?

Thanks in advance.

In form_M exit_from
:global.from_b := 'Y';

In form_A block instance
default_value('global.from_b', 'N'); --not sure of syntax
If :global.from_b = 'Y' Then
EXECUTE_QUERY;
:global.from_b := 'N';
End If;

You may user the trigger WHEN-FORM-NAVIGATE.

Zameer,

As per the functionality description of the WHEN-FORM-NAVIGATE trigger provided by Oracle:

Quote:

Fires when navigation between forms takes place, such as when the user changes the focus to another loaded form.

the suggested trigger should do the job, so when I close FORM_B and I have set the above Trigger on FORM_A the Trigger should fire since the focus comes back to another loaded form. But still it doesn't seem to be working??

in the WHEN-FORM-NAVIGATE trigger I am trying to direct to WHEN-NEW-FORM-INSTANCE trigger in order to reload the form:

EXECUTE_TRIGGER('WHEN-NEW-FORM-INSTANCE');

Why is this not working?

Thanks

Hi,

Calling a oracle builtin trigger like u are trying wont do the job for u. You can copy the entire code in WHEN_NEW_FORM_INSTANCE in a procedure XYZ and call this procedure in both triggers WHEN-NEW-FORM-INSTANCE and WHEN-FORM-NAVIGATE.

Thanks for the tip, I have already done what you recommended of calling a procedure that does the When-New-Form-Instance job,but I still have an issue that the WHEN-FORM-NAVIGATE trigger is not FIRING when I regain focus in FORM_A.

I am trying to display some messages in the Trigger and pausing but it doesn't seem that the Trigger is being triggered???

I tried Exiting Form B either by Exit_form or close_form and still the When-Form-navigate trigger in Form A is not Firing!!!

What could be the reason?

I appreciate your help.

Thanks,
Baz

I still can't understand what's so complicated in this ... I created two test forms and called MODULE2 form from MODULE1 using the WHEN-BUTTON-PRESSED trigger which looks like this:

call_form('C:\Temp\module2');

go_block('dept');
execute_query;

and guess what? Changes I did in MODULE2 were perfectly visible in MODULE1.

Here are those two forms so - if you have a good, old Scott's schema, test it and see for yourself.

Hi,

I tried the same with couple of forms here and its working but it should maintain a sequence.So unless i have a broader picture of what u r trying to achieve i wont be able to provide u a solution.I would like to know how the Form A and Form B is called initially and how the focus goes to Form A automatically.

You may try out the solution above wincy has provided.

Thanks

SOLVED

Littlefoot, you are right the issue here is not complicated but the example you have provided (which definitely works in your case) is different from what I have. BUT THANKS FOR YOUR TIME AND FOR PROVIDING THE SAMPLE, YOU ARE ALWAYS HELPFUL IN YOUR POSTINGS.

I used a conditional WHEN-WINDOW-ACTIVATED trigger instead of When-Form-Navigate with the following code, similar to Wency's code (Thanks for the tip):

If :global.from_DETAIL = 'Y' Then
LOAD_MOVEMENTS();
:global.from_DETAIL := 'N';
End If;

setting global variable to 'Y' from the form I am leaving, and Initializing to 'N' on the return-to form.

WORKS PERFECTLY FINE Cool

All your support is appreciated.

WHEN-FORM-NAVIGATE is still a mystery? after many hours of trials I also chose WHEN-WINDOW-ACTIVATED trigger to get my job done.
Curious still to know how I could get this WHEN-FORM-NAVIGATE trigger finally work Smile

WHEN-FORM-NAVIGATE works with OPEN_FORM. Returning from form opened with CALL_FORM doesnt call this trigger.
But because CALL_FORM works synchronically, solution described earlier works! :

CALL_FORM .......
...........waiting until CALL_FORM ends

YOUR CODE.......
