how to pass argument in a xml and retrive value in class file

Please refrain from making multiple posts about the same issue - its harder to track responses if answers are spread across multiple posts. Please post your onInit code.

I have a action.xml as:







helloworld
dialogcontainer





and the oninit() code :
public void onInit(ArgumentList arg)
{
System.out.println("*** onInit method of HelloWorldComponent called ");
String logType= arg.get("contracts");
System.out.println("****** = "+logType);
super.onInit(arg);
}
It is returning "null".

What happens if you move

super.onInit(arg);

before the first system.out
