When trying to fix a warning like "Event parameter(s) is passed to event method, make sure it is used with right type (change method signature)."
After pressing F1 Quick Fix (and press the button Fix), then Servoy / Eclipse give an unexpected error:
An internal error occurred during: "Save solution data".
java.lang.NullPointerException
How can this be fixed?
I'm afraid there is some corruption in the repository, because even check out of the whole solution in another workspace, is giving this error.
