Hello,

I'm having an issue opening a process that was built in eclipse and loaded into guvnor from eclipse using the web designer.  I'm getting this exception -

I think i was able to view the process before but nothing changed and when i created a new package to load it into i found that i can't open the process.

Anyone have an idea as to what might be causing this?  We want to show to our customers using the web designer because they are remote and don't have access nor do we want them to have access to the eclipse viewer.

We are using jbpm 5.2 and i believe with the newest designer but can't say for sure.

Thanks
