[flexcoders] TypeError: Error #1009: Cannot access a property or method of a null

[priyatalwalkar]

Hello,


I am getting below error while trying to call a action script
function from mxml. When I click on the "Login" button, the function
"private function login
(loginIDParam:String,loginPasswordParam:String):void" generates this
error. I am not able to find out which object reference is null here.

Anyone has faced this issue earlier, please reply me.

Regards,
Priya
