[kepler-users] saving workflow from actor code

[Ufuk Utku Turuncoglu]

When i tried to implement your suggestion, i got following error during 
opening workflow. The actor CCSMConfig2 dir port is connected to diamond 
and it causes error. The workflow is opened without error when i comment 
this part of the code. Any suggestion?

ps: line 442 has effigy.setModified(true); definition.

Thanks,
