CascadingDropDown Problem

Hello everyone,

I'll try to keep it simple and brief. This is another "[Method Error 500]" problem. I looked through all previous posts, but couldn't figure out the solution to my problem.

I'm using AJAX 1.0 RC and the latest version of the Control Toolkit (downloaded yesterday).
I have 3 dropdownlists. Here's how it goes:

1) I select something from DDL1 (DDL2 becomes populated)
2) I select something from DDL2 (DDL3 becomes populated)

until this point everything is OK. BUT, in DDL2, there is aparticularitem that when I select it, DDL3 says "Method Error 500". Other than that particular item, it all works fine.

Notes:
1) My Webservice declaration has the attribute[System.Web.Script.Services.ScriptService()]
2) I debugged the code, the results for this particular problem are returned from the database just fine, no exceptions, no problems.

Any ideas, tips?

Thanks!
