Skip validation phase

Question

Hi
My functionality is user creation. The fields are user name and role.
I have an input text box to enter role name and a command button to search roles using the role name. My form has another input text box to enter user name and it is a required field while creating user. But whenever I am trying to search role I am forced to enter username as it is a required field.
My code is
<h:form >
<center>
               <rich:panel style="width:600px;" rendered="#{appUserBean.createUserPanel}">
                    <f:facet name="header">
                         <h:outputText value="#{msg.corp_createUser}" styleClass="info"/>
                    </f:facet>
                       <h:panelGrid  columns="3">
                    <h:outputLabel for="name" value="#{msg.corp_name}" />
                    <h:inputText id="name" value="#{appUserBean.user.actName}"
                     validatorMessage="#{msg.validation_name_length}"  required="true" binding="#{appUserBean.inputName}" >
                         <f:validateLength maximum="45"/>
                    </h:inputText>
                    <h:message for="name"  styleClass="error"></h:message>
                             <a4j:form>
                    <a4j:outputPanel  ajaxRendered="true" >
                         <h:panelGrid columns="3" id="lovPanel" rendered="#{appUserBean.allowLovPanel}">
                          <h:outputLabel for="role" value="#{msg.corp_org}" />
                         <h:inputText id="role" value="#{appUserBean.role.name}">
                         </h:inputText>
                         <a4j:commandButton  immediate="false" title="Search" value="#{msg.button_search}"
                         image="/images/Search-32.png"  action="#{lovHandlerBean.processLov}" >
                              <f:setPropertyActionListener target="#{lovHandlerBean.backingBean}" value="appUserBean" />
                              <f:setPropertyActionListener target="#{lovHandlerBean.backingBeanAttribute}" value="role" />
                              <f:setPropertyActionListener target="#{lovHandlerBean.lovVisible}" value="true" />
                         </a4j:commandButton>
                         <jsp:include flush="true" page="/jsf/orgLov.jsp"/>
                    </h:panelGrid>
                    </a4j:outputPanel>
                    </a4j:form>
                    <h:panelGrid  columns="3">
                    <h:commandButton  value="#{msg.button_create}" action="#{appUserBean.createUser}">
                    </h:commandButton>
                    <h:commandButton  value="#{msg.button_cancel}" >
                    </h:commandButton>
                    <h:commandButton  value="#{msg.button_reset}" >
                    </h:commandButton>
               </h:panelGrid>
               </rich:panel>
                    <jsp:include flush="true" page="/jsf/viewUserDetails.jsp"/>
          </center>
     </h:form>I want to skip the required validation. Whenever I am using immediate=”true” for the search button. The user role search criterion that is role name is not able to apply.
Please help me
Thank in Advance

Make the required attribute dependent on the presence of the request parameter or the component (submitted) value.
The immediate attribute has a different purpose. To learn more about it, you may find this article useful: [http://balusc.blogspot.com/2006/09/debug-jsf-lifecycle.html].
