Re: Deactivate event for pagepanel

Trap it where you change the page panel, before any of the new text fields are populated. There is some sample code that demonstrates the use of a MessageDialog that halts the execution of code and does not proceed until the user clicks one of the dialog buttons. Check MessageDialog in the LR for example code. It works nicely. It will prevent the new fields from being populated before the previous one is saved or discarded.
