Debugging Zimlets

[mghaught]

Is there a log that tracks the deployment or undeployment of zimlets? My test zimlet seems to hang Zimbra. After login it just sticks in the loading page. The Zimbra.log doesn't seem to have anything in it and I don't recall seeing any mention of a log in the zimlet guide.

Cheers,
Marty

Welcome to our private purgatory... this is usually a javascript error.

Best way to debug this:

Plug your .js code into jslint.com, and fix all the bugs it finds.

Redeploy the zimlet, and load the app in mozilla with the debugger running. Find (in the js console) whatever it doesn't like, and track it down in the debugger...

Most likely a JavaScript error. Run your Zimlet code through a syntax checker like http://jslint.com

If you launch the app with ?debug=3 you may get some more data. Of course it's best to use Firefox and the Javascript console. It may show you the problem.

One more thing - if you reload in the debugger, load the url with
?mode=mjsf&gzip=false
appended to the url, for debugging sanity (takes longer to load, but it's worth it)

Thanks!

You can also load the Venkman (mozilla debugger) and set the following option:

Debug > Error Trigger > Stop for Errors

Then, when loading the client any JS errors will trigger the debugger to stop/break on the exact line causing the error.

Is there any handy documentation anywhere on the various modifiers to the zimbra query string and what they can do? Would be very helpful to have a wiki page somewhere with details.

I've started one here... We can update/add to it as we go along.
