I have a dialog on which I have several widgets and I use JFace databinding to link the widgets to my model. I also use validators for some of the fields (with control decoration support).
The validation of one of the fields on the dialog depends somehow on other fields. To make it concrete: the dialog allows the user to define parameter data (name, type, default value, ...). The default value field is validated depending on the chosen type. So, whenever the user changes the type, the default value field has to be revalidated (and an error decoration needs to be displayed in case of error).
I tried to listen on modification of the type binding and then call "validateTargetToModel" on the default value binding but this doesn't solve my problem.
How can I make sure that the status and visible state of the default value field is updated when I change the type field ?
