Liferay portlet: liferay friendly custom Url parameter

Can someone help me? I have custom parameter, "statusparam" for example. And I want to do something like this:

actionResponse.sendRedirect(redirect + "&statusparam=error");

But the problem is that custom parameter is non-friendly to liferay and liferay doesn't see it in my render method:

String status = ParamUtil.getString(renderRequest, "statusparam");

How can I generate liferay-friendly URL with my custom parameters? Or how can I take them?

There are two ways to get parameter values which don't have namespace prefix.

  1. Add following line in liferay-portal.xml :

    < requires-namespaced-parameters > false < / requires-namespaced-parameters >

and you can read like:

String status = ParamUtil.getString(renderRequest, "statusparam");
  1. Or use HttpServletRequest like:
HttpServletRequest request = PortalUtil.getHttpServletRequest(renderRequest);
String statusparam = request.getParameter("statusparam");

Edit: If you only need this parameter in render method of same portlet, use setRenderParameter like:

actionResponse.setRenderParameter("statusparam", "error");

Remember, it will not add in URL and also will not available in another portlets

Pattern 1: setRenderParameter
One way is to set render parameter(s) in action phase using setRenderParameter as following:

actionResponse.setRenderParameter("statusparam", "error");

and then get using:

String status = renderRequest.getParameter("statusparam");

or

String status = ParamUtil.getString(renderRequest, "statusparam");

Pattern 2: Global property
Other way is to put a global property in action class, assign it value in action method then it would be accessible in render method as well.

public class MyPortletAction extends GenericPortlet {
    String statusparam = "";

    public void doView(RenderRequest renderRequest, RenderResponse renderResponse) {

        if(statusparam != ""){
            // Perform operation as per your requirement
        }
    }

    public void processAction(ActionRequest actionRequest, ActionResponse actionResponse) {

        // Set statusparam here:
        statusparam = "error";
    }
}

Pattern 3: queryString
While, if you want to pass it as queryString parameter, then you can extract it from HttpServletRequest object in render phase as following:

HttpServletRequest request = PortalUtil.getHttpServletRequest(renderRequest);
String statusparam = request.getParameter("statusparam");
