I have textField. When I click on the object, I debug the trace and watch
This shows, mx.core.UITextField.
In the next line, if I do getQualifiedClassName(e.target) I get
Type Error: Error #1009: Cannot access a property or method of a null object reference
What am I not understanding?
Not sure what you mean by “debug the trace and watch”. Make a simple test case and post it if it doesn’t work.
