[jQuery] $('#foo') failing

[jQuery] $('#foo') failing


I have a webapp that uses JQuery (version 1.2) for doing javascript
DOM manipulation. The webapp works great most of the time. However, we
have an easily reproducible bug in which JQuery cannot find a
particular DOM object under certain circumstances, even though the DOM
object does seem to be there. Even worse, if I try to debug the
problem with Firebug, the problem does not happen!
The bug happens on all browsers. And it happened with both JQuery
1.1.4 and JQuery 1.2.
Currently, the webapp is in private beta, so it's not accessible to
the public. However, if you are a JQuery expert and would like to
take a look at the problem, send me an email and I will give you a
login to the site.
Also, I have created a dummy version of the app that includes the UI
and a dummy back-end. If it would be helpful, I would be happy to
send you the source of the dummy version. The app is a java app that
runs under Tomcat or any other J2EE container.
