Problem With Internet Explore And Echo Components

Hello,

I develop a web application in which there are two selectField, I fill those selectFields with two DefaultSelectFieldModel and when the slected item of the first selectField change I change the model of the second one.

Whene I test my application with Firefox it works fien, but whene I test it with Internet Explorer 6 it doesn't work correctly when I load the page: in fact if I change the first selectField's selected item no change succeded on the second selectField, but if I refresh the page by clicking on the browser refresh button it starts to work correctly.

Could anyone help me, please?

Thank you very much!!!!

Bye
