To answer number 2, yes. That's what the component should have been doing the whole time.

Well, I suppose I just got lucky since the only two dojo widgets that I've used from Tacos were exactly the MenuBar and the TabContainer ;) I finally gave up on since I didn't really *need* it, just would be nice to have it. I agree, MenuBar leaves much to be desired but since in my case it's use will be limited it was a very cost-effective solution, really easy to implement. I got my whole menu structure working in a few minutes (well, except for the ajax part). About sam's e-mail, 2 things: 1) I saw the bug in IE in which the menu items appear at the very top. From what I could test it happens because the menu items are always placed at the beginning of their parent tags, for instance: <div> ... some stuff here My menu here </div> This wouldn't work because the menu items would appear at the same place as the other stuff. A workaround would be: <div> ... some stuff here </div> <div> My menu here </div> At least worked for me... 2) I'm not sure I fully understand the menubar/ajax problem. I thought the problem was that the request was executing the javascript code again, when it shouldn't, thus creating a new menubar. I searched the Tacos dev list like you told me to find a "new dojo tapestry widgets" thread but I really wasn't very much enlightened by it. Anyway, please correct me if I'm wrong. I looked at the Tacos source code and the way I see it now, in order to make it work, I'd have to replace the DojoMenuBar2 component with a slightly altered version that will check if the menu (with the same name) already exists before creating it, i.e., not call dojo.widget.CreateWidget when it's not necessary. I'm no expert on javascript, and I don't know exactly if that's what you were thinking. Any ideas?

If you look at some of the other tacos components you'll find that their script templates use the ResponseBuilder to determine if they are in an ajax request and respond appropriately..(Ie either execute immediately or execute upon window/package load depending..) -) The Menu widget ~is~ horribly slow..It was written by some of the same people involved in writing the TabContainer. I hope it doesn't give people a bad impression of dojo devs as this is only one part of the community. I recently added a new "tab like" widget which should be extremely fast..It can do a lot more than just "tabs" as it is very generic, but there is at least an alternative. . http://archive.dojotoolkit.org/nightly/tests/widget/test_RadioGroup_tabs.htm l In fact - the same widget could probably handle dynamic menus + tabs with equal ease as it's based on a UL/OL and css class names. No images/css templates/etc are loaded by the widget. It works completely off of what you give it so there shouldn't be any hidden css behaviour to drive you nuts.
