i guess there is a problem with the extension, because the first call of a method wich is in a extension, causes the trouble, but there are no compileerrors even when i restarted eclipse or cleaned the project

i hope somebody can help me, cause i have no idea what the problem is

best regards

Hi,

can you check the imports/extension statements in your extension files for a missing semicolon.

hello christian
thank you for your fast reply

i checked all extensionFiles in my package and there is no semicolon missing
the extension file which properly causes the problem has only "import uml;"
and nothing else, so maybe the problem is something else

best regards

Hi, one thing you still can do is to try to (java debug) the workflow
and see which file is actually causing the problem

maybe there is somewhere an extension declared with an invalid syntax (missing semicolon in the last line. the parser for the editor may not cpmplain but the one for the backend does.

hallo christian
thanks for your help, now i found the problem
the semicolon was missing at the end of the file, and i searched all time at the beginning. Embarrassed

like almost always little errors can cause big confusion

best regards
