Exception seem in an eclipse GMF application when file not present in workspace
- by rush00121
I am developing a GMF application .
In this situation , I start my workspace and load a file in the workspace . Then I close the workspace and then delete the file from the workspace . After that, I try to restart my application and restore the workspace . Of course , now since the file does not exist , there are going to be exceptions . I tried a lot to handle these exceptions but if I try to get rid of one exception , then another pops up .
Does anyone know what methods do I have to override in order to handle this situation correctly . I am attaching the stacktrace that I get in this exception for a better picture .
