Syntax

@ScopeParam("keyString") 

@ScopeParam(scopes=Scope.APPLICATION, value="keyString")

A list of all scopes enumeration:

enum Scope {
    COMPONENT, SPACE, PAGE, DESKTOP, SESSION, APPLICATION, // single scope
    AUTO //find by comp.getAttribute(name,true)
}

Description

Target: A method's parameter (initial method and command method)

Purpose: Tell binder to retrieve a value with specified scope

The default scope: AUTO means searching the value from COMPONENT to SPACE, PAGE, DESKTOP, SESSION, APPLICATION one bye one automatically until find a non-null value. If you specified the scopes element, binder will search the only scope you specified.

	@Init
	public void init(@ScopeParam(scopes=Scope.APPLICATION , value="config") String sysConfig,
			@ScopeParam(scopes=Scope.SESSION,value="user") String userCredential){
	}
