Need to clear the form and execute a procedure in same trigger [message #522713]

Hi all,

I have a problem in my form.
In my form there are 4 blocks and in one of the block i have a button. In which i put a code same as below:

BEGIN
     IF NAME_IN('SYSTEM.FORM_STATUS') = 'CHANGED'
     THEN
        CLEAR_FORM(NO_VALIDATE);
     END IF;
    PROCEDURE ABC;
END;

So as per code i want to clear all the changes in form for current session and want to call the procedure ABC after that.
But it is not calling the procedure ABC.

Could any one please let me know why this is not executing?
And what would i do to perform the same?

Regards,
Umashankar Jhajharia

What makes you believe it's not calling the procedure?
The only way that could happen is if clear_form raised an error. Do you have an on-error trigger?
Put messages before and after the clear_form command and at the beginning of ABC and see if they appear.

Yes.
I already tested that.
Before CLEAR_FORM, the message is appearing but after that nothing is executing.
No message after running of clear_form.

What is this

procedure abc;

line really? I suppose this is just an illustration, I don't think that procedures are called that way.

Also, the way it is written now, the procedure is executed nevertheless the form status is 'CHANGED' or something different. So - maybe the procedure uses certain values you cleared so it does nothing when these values are missing.

In order to debug it, put MESSAGE built-ins into this trigger, as well as into the ABC procedure so that you'd know what was (or was not) executed.

It would help if you showed us the real code.

And you didn't answer my question about the on-error trigger. If you have one delete it and try again.

Hi Cookiemonster,

There is no 'ON_ERRO' trigger in block level but there is on form-level.

CODE:
-----
BEGIN
IF NAME_IN('SYSTEM.FORM_STATUS') = 'CHANGED'
THEN
message('start clearing of form');
CLEAR_FORM;
message('End clearing of form');
END IF;
message('Navigate to next-form now');
ABCD('NEXT-FORM');
END;

The code is as per upper one.
First message 'start clearing of form' is displayed.
After this both the messages are not displaying.

ABCD is a procedure which is taking another form name as argument which is being navigated by NEW_FORM in that procedure.

Is there any other way to resolve this problem without deleting that on-error trigger.

Why is this code in an ON-ERROR trigger? What you are saying is: whatever error happens (and was not captured elsewhere), this trigger will. And what will you do? Clear this form and call another one.

Is this really the way you want to handle errors?

Deleting the on-error trigger is a temporary measure to see if it's masking an error. So try it and see what happens.

Hi all,

Please leave it all.
Just i want a solution on broad level.

I have a button on a form which is calling another form by using NEW_FORM. In this case if i am changing anything on first form, whenever i am pressing the button, it is showing a dialogue box as "'Do You Want To Call the New Form?'.

Now what should i do if, i dont want this message here to pop-up.

Thanks for your feedbacks.

Have you tried calling it with the full_rollback parameter?
If that doesn't work then you probably can't get rid of that message.

Can we write something by which all the changes performed in same session could be undo in same WHEN-BUTTON-PRESSED trigger ?

Also, I suppose that "all changes" should have been "all uncommitted changes"?

Yes.
I don't want to commit the changes in same session.

Then you need to use clear_form, or if there's just one datablock clear_block should do.

Is it TRUE?
When i will use clear_form it will load the SAME FORM with new session.
And where will be the cursor of execution after clear_form statement.

clear_form clears all the items in the form. It doesn't load anything. It doesn't start a new session.
As for the cursor - try it and find out. 1st item in 1st block probably.
