Post by manuknecht on Specify Input Configuration "OnDialogClosed" Action to only react to certain Dialogs ^{CODESYS Forge talk (Post)}
Thanks for your responses. The close listener sounds like an interesting approach, will have to see what I can do with it. I actually solved it as suggested by sturmghost by setting an enum variable to a certain state as soon as I open a dialog. This way I always know which dialog was opened last.
