Summary	0004015: Expression "jumps" to new object when created
Description	An expression using an object referrer can inappropriately "jump" to a new object when this latter is created. From first investigations, it happens only if referrer is the object label, not if it is its (internal) name. --- Forum thread
Steps To Reproduce	From a blank new design : Go to Part WB and create a cube => Will be labeled "Cube" in the tree view Add a second cube (=> Will be labeled "Cube001" in the tree view) then set its Z position as being "Cube.Length" Add a third cube (=> Will be labeled "Cube002") ==> Ouch ! FreeCAD immediately complains about a cyclic dependency. If you look back at Cube001 properties, its Z position has "jumped" to Cube002.Length instead of Cube.Length --- It doesn't happen if internal name is used in expression (i.e. Box.Length instead of Cube.Length), but FreeCAD however complains about a cyclic dependency.

openBrain 2019-12-17 12:23 developer ~0013931	@ezzieyguywuf : I can't no longer reproduce it. Maybe the 'Big Merge' solved this. Anyway, I'll tag ticket to be closed.
