Microsoft AJAX toolkit controls in Aqualogic UserInterAction portlet?

Question

using .NET accelerator
6.1 MP1 portal version
.NET 2.0 framework
I created website project using ALUI template in VS 2005. Then I copied over the web.config settings from a AJAX control toolkit website project in VS 2005 figuring this will "map" all the settings.
Upon loading the portlet I see a javascript error : "this._form" is null or not an object.
Has anyone been able to successfully implement MS ATLAS ajax controls into their portlets?
If so please clue me in on how you did. Examples much appreciated!
Thanks in advance.

In my experience, ALUI doesn't play nice with the Ajax Toolkit (6.1 ALUI and portlets written in .net 2.0).
But, if you want to go ahead with it, one solution is to write your own Response Filter to append the portlet ID to the ToolkitScriptManager initialization statement (essentially doing what WC3.1 does to all the other objects, including the form you want to apply the script manager to, which creates the issue).
You can write a filter as detailed at http://aspnetresources.com/articles/HttpFilters.aspx ; that article is about filtering for xhtml compliance, but it's a good walkthrough on how to create a basic filter. To append the portlet ID, we use StringBuilder.Replace() for the appropriate string. I also recommend following the advice of comment 46 of the discussion page for that article and using the Flush() method (instead of the Write() method of the Filter, which worked in simple cases for us but not bigger pages with multiple controls).
Note that after you write your filter, you don't need to call it from an HttpModule unless you want to. We're having good luck just calling it from the page the script manager is on. In other words, in your Page_Load, just put:
Response.Filter = new PTFilter(); //or whatever you want to call it
