Our code (box.js) uses jQuery in noconflict mode by default and we use "jQuery" instead of $.
I think the following solution from
http://groups.google.com/group/jquery-en/browsethread/thread/9737e52028077d5c/f4a45f44c44bb3fa
might help:
"I found a solution that works perfectly. I'm the live example that we need sometimes to use the both frameworks. I'm develop all my projects in jQuery, cause I learn more easily and feel more comfortable with it. Nothing to do with Mootools, with is a beautiful framework too... But I need the fancy upload to work and is just possible with Mootools, I make everything, but doesn't work because the conflict with the variable $event. I solve this issue by getting the mootools download with no compression, use a software like aptana, dreamweaver, or even notepad to replace all occurrences of $event to $event2 for example, and compress
the library after it. This way, the two frameworks works perfectly, since the use of jquery with noConflit its configured. I hope this works and soon I will develop this fancy upload for jquery to don't have to use both. Its a shame for the mootools team wait to Jquery solve this
problem that noboby its blame... its just convention... why just simple replace $event for $mootoolsEvent or $mooEvent for example??? Sometimes its necessary use both, no doubt.."
