Uppdate a WSDL definition which has a renamed interface

Hi guys,

I am trying to update a WSDL definition in SoapUi, but after the update is complete, I can not run my tests. Exception is thrown. I tried a Google search but with no success. Here is my scenario:

I have test cases that were written againt a service with one endpoint - let's say the Interface is named Interface_1. All the tests were green and everything worked fine.

However, now I have this service updated with new interface, named Interface_New, and the first interface RENAMED to Interface_Renamed. After I update the interface through the context menu, the tests fail to execute.

Is there anyone familiar with the WSDL update when there is an Interface renamed?

This is the exception:
