RE: JPA Controller Generation

[Kenneth Fogel]

JIRA refused to accept my upload of a document that outlines my issues 
concerning the JPA generator. The file is available as a PDF or a Word docx. 
Both are refused with a message about a missing token. I do have a JIRA login. 
I will email it directly to you but I'd like to have it recorded on JIRA.

Thanks for reporting this issue Ken.  It would be good to get something in the 
issue tracker for this problem.  I haven't used the auto-generation of new JPA 
controllers.  I usually create my own so I haven't come across this issue...but 
I'll see if I can replicate this problem.  I may not personally be able to make 
the repairs for this (at least not anytime soon), but it should at least get in 
the tracker so that we can have it in the queue.  It does sound like this code 
needs updating.

It sounds like you have a good strategy for moving forward with your class.  
Hope all goes well.

Thanks

Thanks for getting the thing started..

P.S. I hope https://github.com/apache/netbeans-website/pull/450 will do the
trick

I KNEW if I touched it I would blow up the whole thing.  I looked at the
page to see it it had changed this a.m.  It changed alright but not for the
better I fear.

It seriously needs your attention (spell that "fix") again, Geertjan!  Or
somebody else who knows what they're doing.  I don't see the difference
between my link and those that follow.
