Re: [Dltk-dev] model exception being thrown

["Jae Gangemi" <jgangemi@xxxxxxxxx>]

  i've done some more investigation and it appears that this problem only occurs if the file being edited is not contained within a source folder.

  sample project dir structure:

  perl
    lib
      Class.pm
    sample.pl

  if i make changes to Class.pm, i can save them w/o issue. if i make changes to sample.pl (which is NOT under 'lib'), i get an error when i try to save the file.
 
  this used to work and it should be a valid to have 'scripts' that sit directly under the project root directory.

  i've tracked down part of the problem.

  the SourceModule object being returned from getSourceModule() in CommitWorkingCopyOperation.verify() claims that it is not the working copy.

  what would cause that?

the exception is thrown from ModelStatus after verify() is called

I don't recall having to make changes for the ISourceElementParser change but maybe I missed something

I'll provide a stacktrace once I get to the office

Hi Jae,

The recent incompatible change was the
ISourceElementParser interface change - but old code just would not compile, there should not be any exception thrown.

If you post more details like location where the exception is raised - it should be easier to find out what happens.

Regards,
Alex

hello all -
 i keep getting a 'operation not supported' error message when i try to save changes to my editor.
 my guess would be that something changed in the core that requires me to update some code on my end, but i'm not sure what that would be. anyone have any ideas?
