.net-1.1

Hi, I have a ASP.NET 1.1 application, and I'm trying to find out why when I change a ComboBox which value is used to fill another one (parent-child relation), two postbacks are produced.

I have checked and checked the code, and I can't find the cause.

Here are both call stacks which end in a page_load

First postback (generated by teh ComboBox's autopostback)

Postback call stack

Second postback (this is what I want to find why it's happening)

alt text

Any suggestion? What can I check?
