Error when Creating Web Dynpro Model in CAF-Service

Question

Hi All,
I reaaly need help. AFter updating to SPS 9, it was necessary to redeploy my Entity Service. That contains to "Create a Web Dynpro Model" in the Service Explorer,
to get an interface of the Service in my Web Dynpro Application.
Before I update to SPS 9, the Application works fine.
But now, when I want to "Create a Web Dynpro Model" in the NWDS I get the following Error-Message (its not a useful Error-Message):
<i>Error cannot create Web Dynpro Model:
Creation of  Web Dynpro model failed. Reason: null </i>
Thanks for helping me
Steve

Hi Aliaksei,
the problem in the thread is the same I got.
When I use only 7 letters for the operation name, the creation work. When I use more then 7 letters the creation doesnt work.
But its hard to find a methodname with only 7 letters.
In SPS 8 I didnt have problems with the length of method names. Why is it so?
