Retrive the Request from an AbstractUICommand

Hi Experts,

In order to retrieve the request into an UI Command Java class which inherits from "AbstractUICommand", i have used that code :

IPortalComponentRequest pcr =(IPortalComponentRequest) getProxy().getDynamicPage().getPageContext().getRequest();

The problem is that the getProxy() method return null, thus i can't retrieve the request !

What should I do to solve this problem?

Best Regards

Hassan
