RE: [flexcoders] Why am I getting an "error accessing null property"

2006-10-18 Thread Iko Knyphausen 












Try 

Alert.show(textVar,
‘Message’)

 

Make sure you have the control imported

 

    import
mx.controls.Alert;

 

also make sure that the first argument
in the show method (“show” in lowercase, btw) is actual a string
type. You may need to use the .toString() method to get there

normally this means that you are trying to access something that is
not created yet.. what did you put in the Alert.show?

Maybe there are no results, or the fields aren't what you think.
What does the debugger say is the value of event and event.result ?

Well, you haven't imported the Alert class, and also I 
don't see you initializing the ModelLocator
