Problem with FRM-40403

Question

I'm getting the following error when trying to commit a form in Forms 6i
FRM-40403: A calling form has unapplied changes. Save not allowed
The scenario is the following:
I have Form A which calls Form B, when I save Form B I get the error and nothing is saved on that form... The problem is that I have another form, lets called it Form C which also calls Form B and I am able to save Form B there... the call I'm doing its exactly the same in both forms A & C,
CALL_FORM('FORM_B', NO_HIDE, DO_REPLACE, NO_QUERY_ONLY, pl_id);
I googled the error but the only workaround I found is using OPEN_FORM to use another session, it actually works but then I loose some global variables I set in Form B so I can use in Form A; and the actual course of the code after doing the call_form doesn't execute.
Any ideas what could it be??
Thanks in advance

Answer 1

you mean all the changes to the form?? Its sounds kinda complicatedThe problem:
If you use POST in a form, all outstanding changes will be applied against the database (INSERT's, UPDATE's, DELETE's are executed), but there is no final commit sent to the database. But.. forms treats the status of all objects as applied (means the record-status of all records is QUERY, the Form-Status is QUERY). If you now exit the form, forms will not ask you "Do you want to save the changes" for there are no outstanding changes. But... If the forms is exited, there will be no commit executed and therefore the formerly applied changes are lost.
To avoid this, you have to "remember" that you posted in some variable and check that variable additionally to the Form-Status, something like
IF :SYSTEM.FORM_STATUS='CHANGED' OR :GLOBAL.MY_PERSONNEL_COMMIT_FLAG='Y' THEN
  -- now ask for "Do you want to save the changes"
  -- and do a COMMIT_FORM if answered with yes
END IF;
