Hi,

It seems that Dojo does not allow users to customize the look and feel of tooltip dialogs individually, i.e., different CSS when there are multiple tooltip dialogs on the same page. The reason for this is that when the tooltip is opened, the class information associated with the widget is deleted silently. This seems like a bug which should not be too difficult to fix.

Here is a demo page which shows this behavior: http://queens.db.toronto.edu/~nilesh/misc/dojotooltipcustomization/

thanks
