In my Project (FB4) I use the "Create Zip File" action, this runs fine in FB4. Loading this Project in FB5 I needed to turn of Validation because Validating the Project it says: Files: No files have been sellected to add to the zip file for the Create Zip file action. This is true from the static point of view, but since I'm adding files in the BeforeAction event with the statement: Action.FileList.DelimeterText = "SomeVariable" this could be ignored. In FB4 the project validates just fine.
What do I need to do to get this action to run with Project Validation switched on?
To disable "Validate Before Run", go to Tools -> Options -> General IDE Options -> Validation.
However, what is probably a better solution for you is to just put a dummy value into the files list property in the GUI, so that the action passes validation. When you set the DelimiterText property then you will be overwriting the existing value, anyhow. (or you can call Action.FileList.Clear().)
That way you still get validation for all other actions.
