Posted on by maram fraij

A new two customized fields are added to HCMEmployment table, in HCMWorker form I need to perform the following:

-If the value of the first customized field is not zero and the value of the second customized field is still zero , the form should not be closed anda waring message should be displayed for the user saying that this field should be filled.

The required checking and message code is added to ValidateWrite method on HcmEmployment datasourse on the Hcmworker form, the question is how can I prevent closing the HCMWorker form ?????

Hi Maram

You have set the Ret variable to False ? E.g.

public boolean validateWrite()

{

boolean ret;

ret = super();

if ( .... )

ret = checkFailed("Error");

return ret;

}

If Ret is set to False, you prevent the form closing.

Regards

If you add a validation to validateWrite(), it's executed automatically when a record is being saved. Normal closing a form tries to save modified records automatically and it executes validateWrite(). If it fails (the method returns false), the form is not closed.

If the form is left without saving or there're no modified data, validateWrite() is not called, of course.

If you want a validation when closing a form regardless whether a record is being saved, validateWrite() is not a good choice. Use canClose() on the form instead.

I try to use can close () method, but the problem I face is that when from is not closed because of incorrect value for second customized field as required, and the user modifies the value of the that field and the form is closed successfully, the modified value is not saved what should I do ?

You said that "the modified value is not saved", so my question is how you're saving it. Can you show us your implementation and describe the observed behavior?

Nothing is added to prevent saving the modified data. I noticed this behavior I assume that after modifying the value and the worker form is closed successfully the new value should be saved but I find the original incorrect value which prevents closing the form, that means saving for the modified value is not performed.

overwrite canClose in the form

look in the AOT , there is a lot of examples

public boolean canClose()

{

boolean ret = true;

if (this.closedOk())

{

if (agreementLineRecId != aLine.RecId) //only check if another agreement line is selected.

{

ret = aLine.canLinkTo(salesPurchLine);

}

}

if (ret)

{

ret = super();

}

return ret;

}
