In some scenarios, it's possible that an object is created on Canvas which later somehow gets corrupted, meaning it's still somehow part of the Canvas definition, but not accessible anymore.
This can probably have various effects; a known one is that such object ma prevent easily adding new objects of the same type, because it "occupies" the object name which otherwise would be used for the same object.
While the known scenarios and root causes where this can occur should be fixed, it might be useful to have a functionality where such corrupted object is automatically found when a Canvas is loaded, and then removed. Jedox already has a similar capability for spreadsheet objects.
