InvokeMethod and enabled/disabled

Question

Hi.
I have created AM implementation and add new method. Exposed it to client.
And by drag'n'drop-ing this exposed method to JSF there is a button which executes this method.
By default on this button there is one property Disabled which is set to #{!bindings.methodName.enabled}.
How do I handle enabled/disabled from my AM implementation? My logic for disabled toggle is very complex and I want it to put it in Java implementation not inside EL.
Thx
Regards
Boris

On my PageDef there is a
  <methodAction id="methodName" RequiresUpdateModel="true"
                  Action="invokeMethod" MethodName="methodName"
                  IsViewObjectMethod="false"
                  DataControl="AppModuleDataControl"
                  InstanceName="AppModuleDataControl.dataProvider"/>I can add permission to that method action like
  <methodAction id="methodName" RequiresUpdateModel="true"
                  Action="invokeMethod" MethodName="methodName"
                  IsViewObjectMethod="false"
                  DataControl="AppModuleDataControl"
                  InstanceName="AppModuleDataControl.dataProvider">
      <permission xmlns="http://xmlns.oracle.com/adf/security"/>
    </methodAction>How do I implement that permission(s)?
