TestStep "Run TestCase" works different in 1.5.0 (Snapshot)

A TestStep of type Run TestCase does not work similiar to SoapUI NG 1.4.1 and older versions. If you use Run Mode: Create isolated copy for each run (ThreadSafe) the property values are always copied to the target testcase which will be executed by the Run TestCase.

This issue caused the following unsightly side effects:

• The default Target-TestCase properties are changed after every execution (not comaptible with version management tools - in my case SVN) - also if you set the option Does not set empty TestCase property values :robotsurprised:
• You can not use and define default values in your Target-TestCase
