Programming forms in cadence

I have been programming forms the last days.
This process is as follows, that the user fills in some fields and
presses "OK".
Then the callback is called and processes the input given.

The issue is following: if the user gives incorrect data, the callback
cannot execute correctly and has to quit. Thus the user has to start
the form again to reenter all the data.
How can this be prevented ?

if the callback detects invalid data, how can the user be sent back to the
already-filled-out form, correct it and try "OK" again ?

Isn't this why there is always an 'Apply' button in Cadence forms?
This would apply the data without closing the window.

 

When the form is created, pass:

?unmapAfterCB t

as one of the arguments to hiCreateAppForm().

This ensures the form is not unmapped until after the form callback. If,
during the callback, you determine the form should stay up, call:

hiSetCallbackStatus( r_form nil )

before returning. If it is OK and should close, call:

hiSetCallbackStatus( r_form t )

, correct it and try "OK" again ?

.... works perfect!
thank you man!
