Some of the objects in a PBL (PowerBuilder library) cannot be exported, deleted, regenerated. And library itself cannot be optimized. Even those objects cannot be edited and neither their source is opened in editor.
I copied the original object from backup to replace the corrupt one but after that library painter shows me two objects of same type and name. One of them is corrupt and still cannot be deleted. The other i copied from backup is opened and deleted.
How to get rid of those corrupt objects from the library?
