Comment on attachment 124964 [details] _ClassDiagram_UI is a class diagram in the SahraCore/UI folder. it doesn't open or delete. The appended xmi file is somehow corrupted. It contains one class diagram named 'class diagram': <diagram showopsig="1" linecolor="#ff0000" snapx="25" showattribassocs="1" snapy="25" linewidth="0" showattsig="1" textcolor="#000000" isopen="1" showpackage="1" showpubliconly="0" showstereotype="1" name="class diagram" font="Sans Serif,10,-1,0,50,0,0,0,0,0" canvasheight="0" canvaswidth="0" localid="-1" snapcsgrid="0" showgrid="0" showops="1" griddotcolor="#f6f6f6" backgroundcolor="#bdbdbd" usefillcolor="1" fillcolor="#ffffc0" zoom="100" xmi.id="uwbRU2dwxj3QB" documentation="" showscope="1" snapgrid="0" showatts="1" type="1"><widgets/><messages/><associations/></diagram> which is referenced later in the section for the tree view <listview> ... <listitem open="0" type="807" id="uwbRU2dwxj3QB" label="class diagram"/> a few line below there is also the class diagram you are missing: <listitem open="0" type="807" id="ucJia8aOVztKv" label="_ClassDiagram_UI"/> but there is no related <diagram> tag in the file. I suggest to open the xmi file in an editor, remove the mentioned line, save the file, load it with umbrello and recreate the diagram _ClassDiagram_UI. If you can give some information how to reproduce this issue, it would be possible to fix this isssue inside the umbrello source code.
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.
