I am not using modules and I also tried to comment out the
ObserveValue tag to see that was causing a problem. Here is the
error message. I am not sure how to read these things to help me!
Thanks, Kevin

Are these things in modules? If so, you might have the shared code
problem. What’s the full text of the error?

Subject: [flexcoders] PopUp Returning NULL
I am having some trouble with a popup window. Here is the popup code:
private function changePassword() : void
{
var pwWindow:IFlexDisplayObject = PopUpManager.createPopUp
(this, WinChangePassword, true);
}
if I call it from a Link Button I get a "Can't Access Property of
Null Object"... error.
<mx:LinkButton id="chpw" label="change pw" click="changePassword();"/>
However, when I call it from the ObserveValue Component I am using,
it works fine.
<ac:ObserveValue id="pwchange" source="{model.changePw}"
value="{1}" handler="{changePassword}" />
Also, when i check the debugger in both cases it shows pwWindow =
null. (I am not sure what it is supposed to be.)
Thanks for the suggestions.
