I have a service model with contains one VF using a VSP (heat template). I created a new version of the VSP to include heat template changes.

When i try to update the VSP version at the VF level using the "Save" button i get a 500 error.

This process was tested with ElAlto and Frankfurt version of SDC with both version failing at the same place. It was also tested with different heat template included the vFW-vSinc one. In the screenshot the heat template used works fine since i was able to perform a full E2E instantiation in openstack through SO.
