Hi Guys
I am trying to implement the login form . The login form works fine
when i use script and put all the action script in the main mxml file.
But my requirements is to put all the action script in external as
file and make things working. For some reason the builder does not
like my login button, user name text and password text in the as file.
Initially it does not recognize those components but then i user
parent::loginbutton to access which solves the compile time problem,
but gives type coercion error in my project as
"TypeError: Error #1034: Type Coercion failed: cannot convert
mx.containers::[EMAIL PROTECTED] to Namespace."
I like to define my login and password text input in the main mxml
file and like to write the business logic in external as file.
Please let me know what i am missing.If you can provide someone who
has done that, that will be helpful too.
Thanks a lot for your help.
