--- Comment #2 from Hamid Sahraiee <sahra...@gmail.com> --- Thanks a lot. by removing that line, my problem fixed. I work on this project for more than two months, therefore I don't remember what I do that cause this corruption. Is there any tool to check the Umbrello file [xmi] and find the failure issues? Is there a log file in the Windows platform that can be accessible after the crash? I think there is more issue in my project file. when I try to Generate C# code on some codes (Not all), the Application will be crashed.or inheritance will not be applied in the generated C# codes. I started the project with Umbrello V 2.29 and then upgraded the Umbrello to V 2.30.0 and continued the development. -- You are receiving this mail because: You are watching all bug changes.
