[kepler-users] Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException...

[J. Marc Edwards]

I'm trying to open a Kepler workflow using the "File -> Open" on the GUI and am not receiving a file chooser window from which to select the workflow. 


This worked with no problem on this server that I am using this version 2.2 of Kepler. However, I did notice that I was asked to upgrade a Kepler module last week when I was starting Kepler. 


I notice a Java exception message that is being printed when I try to open a file. I've pasted the messages below. 


Any thoughts? 


Regards, Marc
