How do you troubleshoot zimlets?

I've had a zimbra support ticket open for two weeks now and all that they do is remove the zimlet and ask me to try again. Over and over without any results.

I don't get any errors in the mailbox.log but the zimlets will just not display.

I have been using these zimlets for a couple years with no problems until version 6.

I cannot find any information on how to troubleshoot a zimlet. Is there a verbose mode I can put it into? Is there some way I can modify it to be more verbose? Is there some magic that can be done to see what the problem is? I am seriously at my wits end. This is a production system and I am seriously worried about the state of the upgrade.

I've read this: ZCS 6.0:Zimlet Developers Guide:Troubleshooting - Zimbra :: Wiki

But that doesn't exactly give me much direction.
