The only time i ran into that issue is when i had walter.brame's version of the PDF Generator in my instance and found that it had some differences in the supporting script includes. Once i backed that out the error went away. Is there a chance you have that update set active?

Yes,   Walter's PDF Generator was installed. I tried to back it out but for some reason I can't back out the app. Filed a support request. Should I back out your app as well and then reintroduce it to the instance?

You should not need to as my update set was independent of any updates, but if you see a problem still after backing out the older PDF Generator let us know.

Thank you so much.

Another question. I am new to SN and was wondering what I would have to do to use your app within a scoped application? I have to protect the tables in that application because the contain sensitive data.  

Again, thank you so much for your contribution. It looks great. Now I just have to make sure I can back out Walter's app.

Last time i checked some of the supporting plugin script includes are set to only be available in the Global application. It might be easy enough to set the GenDocForm to be available in all scopes and you can create an updated UI Action to call it from your scoped app. Let me know if that works.
