I think there is a bug in the Sys.UI.Control

Hi,

I took the sample how to create control that itherits from Sys.UI.Control here

http://asp.net/AJAX/Documentation/Live/tutorials/CreatingCustomClientControlsTutorial.aspx

and I modified the script so that it contains a default value for the "id" property, according to the sample here

http://asp.net/AJAX/Documentation/Live/ClientReference/Sys/ComponentClass/ComponentCreateMethod.aspx

$create(Demo.HoverButton, {id:'testId',text: 'A HoverButton Control',element: {style: {fontWeight: "bold", borderWidth: "2px"}}}, {click: start, hover: doSomethingOnHover, unhover: doSomethingOnUnHover},null, $get('Button1'));

you can find the whole code I used at

http://www.ninebytes.com-a.googlepages.com/DemoHoverButton.aspx.htm
http://www.ninebytes.com-a.googlepages.com/HoverButton.js.htm

or ZIPped
http://www.ninebytes.com-a.googlepages.com/DemoHoverButton.zip

However, I am getting an error "Sys.InvalidOperationException: Operation is not vallid due to the current state of the object."

I think this must be a bug in the framework, as the code is according to the documentation.

Or, does anyone know about another way how to set the "id" property of the control?

(Sys.UI.Behavior works fine)

best regards

Miroslav
