One more thing:
somehow if I press in that Dialog the [OK]-Button it is not closing there is only a message "hiFormDone(_ddsFB_CelldocuInputForm)". I have to press [Cancel] in order to exit. Is there a workaround for that?
2nd) And I was wondering if there is a function or way, that if I resize the for, that all the elements will resize themselves, too.
So if I resize the window from 500 to a width of 400 the StringField should be 380 instead of 480 as well.
