Something wrong with the new expression parser apparently...

Program received signal SIGSEGV, Segmentation fault.

The strange thing is that making a Draft Clone of the object, then changing its scale property (which is what Draft Scale does) works normally...

This is caused by a problem with resolving the property, almost as reported in

Committer: wmayer Details Diff
ObjectIdentifier: Reworked resolve() function to solve issue 0002389 and 0002418.

* Refactored code; moved mutable fields into a separate inner class.
* Added resolvedProperty to ResolveResults class.
* Set resolved document name, even if it does not resolve correctly, so we can give a better error message later.
* If the document name is explicitly set, and it does not resolve, don't try any further.
* If document name is set, use that instead of the ObjectIdentifier's owner when looking up the document object.
