I tried (unsuccessfully) to update a file from SVN. The file was displayed in blue (locally modified) and I wanted to see the differences between the local copy and a remote copy. I clicked on Subversion --> Diff and the AsserionError alert popped up although the diff worked fine. I have attached the messages.log file.
No message.log's been attached, did you submit the error from the IDE (using the exception reporter)? Could you upload the log file manually?
Created attachment 101772 [details] The content of the messages.log file.
I can see what happened. I did attach the file but failed to provide one of the required fields for the bug. The error messages said "Please press the Back button and correct the error". This is exactly what I did. All the fields that I had previously filled where still there so it didn't occur to me to check the uploaded file - it seems that pressing BACK to correct an error wipes out all uploaded files which have to be uploaded again.
the assertion's coming from org.netbeans.modules.ant.grammar.AntHighlightsContainer
