            Add a @WindowDisposed annotation to the ViewScoped beans.

            Surround the set tag with a c:if tag:

                            <c:if test="#{not empty param['testParam']}">
                                <c:set var="testParam" scope="view" value="#{param['testParam']}"/>
                            </c:if>

            Description

            A NPE is thrown when a c:set tag attempts to set/get a URL parameter that is not there. Sample code:

            <c:set var="testParam" scope="view" value="#{param['testParam']}"/>

              Modified EnvUtils.containsDisposedBeans method to test first for null attribute value before testing for WindowDisposed annotation while searching for WindowDisposed annotated beans in view scope map.
