    Problem AJAX Rerendering Date selected from rich:calendar

    Alan Gross Newbie

      I have problems with a date selected from rich:calendar when ajax rerendering.

      Here is the example code:

      <a4j:outputPanel id="filterOptions" layout="block">
      
       <rich:calendar value="#{timerepHandler.selectedDateStart}"
       rendered="#{timerepHandler.filterOption =='1'}" locale="en"
       popup="true" datePattern="dd.MM.yyyy" showApplyButton="false"
       cellWidth="24px" cellHeight="22px" style="width:200px" />
       <rich:calendar immediate="true" ajaxSingle="false" value="#{timerepHandler.selectedDateEnd}"
       rendered="#{timerepHandler.filterOption =='1'}" locale="en"
       popup="true" datePattern="dd.MM.yyyy" showApplyButton="false"
       cellWidth="24px" cellHeight="22px" style="width:200px" />
      
       <h:inputText value="#{timerepHandler.selectedDateStart}" />
       <h:inputText value="#{timerepHandler.selectedDateEnd}" />
      
       <a4j:commandButton value="Refresh List" reRender="test123"
       action="#{timerepHandler.getReportList}" />
      
       <h:panelGrid id="test123">
       <h:outputText value="#{timerepHandler.selectedDateStart}" />
       <h:outputText value="#{timerepHandler.selectedDateEnd}" />
       </h:panelGrid>
       </a4j:outputPanel>
      


      1. In the outputPanel "filterOptions" I select a start and a end date.
      Option A: select the date from rich:calendar
      Option B: Enter the date manually in h:inputText

      2. When clicking the a4j:commandButton "RefreshList" the panelGrid "test123" is reRendered.
      3. In the panelGrid "test123" the dates are displayed

      For some reason Option A (rich:calendar) is not working. Option B (inputText) is working perfectly.

      Has anyone a clue why this is not working? Maybe a bug?
      Thank you very much for your help!

            I'm still debugging on this issue. I'm now trying to get this to work without rich:calender using normal h:inputText. Now I found out, that rootcause of the issue is about the rendered attribute:
            rendered="#{timerepHandler.filterOption=='1' }"

            This code is not working:

            <h:form>
             <h:panelGrid class="vertical-menu-cell" columnClasses="optionList"
             columns="1" cellspacing="0" cellpadding="0">
             <h:outputText value="Select Filter Option" />
             <h:selectOneRadio value="#{timerepHandler.filterOption }"
             layout="pageDirection">
             <a4j:support event="onclick" reRender="filterOptions" />
             <f:selectItem itemLabel="All open" itemValue="0" />
             <f:selectItem itemLabel="Date Selection" itemValue="1" />
             <f:selectItem itemLabel="Current Month" itemValue="2" />
             <f:selectItem itemLabel="By Project" itemValue="3" />
             </h:selectOneRadio>
             <h:panelGrid id="filterOptions" layout="block">
             <h:panelGrid rendered="#{timerepHandler.filterOption=='1' }">
             <h:inputText value="#{timerepHandler.selectedDateStart}">
             <f:convertDateTime pattern="#{cont.datePattern }" />
             </h:inputText>
             <h:inputText value="#{timerepHandler.selectedDateEnd}">

            The only difference is the rendered attribute on this line:
            <h:panelGrid rendered="#{timerepHandler.filterOption=='1' }">
             <h:inputText value="#{timerepHandler.selectedDateStart}">
             <f:convertDateTime pattern="#{cont.datePattern }" />
             </h:inputText>
             <h:inputText value="#{timerepHandler.selectedDateEnd}">
             <f:convertDateTime pattern="#{cont.datePattern }" />
             </h:inputText>
             </h:panelGrid>
            


            Please any help is appreciated. I would love to make use of AJAX intensively, but to me it seems to work very buggy at the moment? Or do you just use it the wrong way. Thank you for your support!

              Alan Gross Newbie

              I would like to clearify one thing:

              The problem is that the value of
              - #{timerepHandler.selectedDateStart}
              - #{timerepHandler.selectedDateEnd}
              is always the default value.

              Field changes are not processed correctly on ajax rerendering. As soon as the mentioned "rendered" attribute is removed everything works perfectly!

                Is timerepHandler bean request-scoped?

                  Yes. timerepHandler bean is request scoped.

                    Hi Nick.
                    I found the case RF-3154 (https://jira.jboss.org/jira/browse/RF-3154?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel) that seems to describe this behaviour. I changed now the scope of the bean to "session" and it is working now.

                    So do I understand it correctly? The main issue is that jsf is not binding components to the backing bean that aren't rendered. This means that every page containing ajax hide/display functionality needs to be managed by a session-scoped bean.

                    What is the impact for the whole application? I mean is it a good idea to have many session-scope beans?

                    Thank you very much for your hint. At least is is working now!

                      Hi Alan,

                      JSF stops request processing for the components that are not rendered. And it doesn't store value for #{...} attribute, but an expression; so on the sequential submit the expression is re-evaluated again and now it's false. It's very common issue.

                      Solutions:

                      1. Use session-scoped beans
                      2. Seam conversation
                      3. a4j:keepAlive
                      4. State Manager API: http://livedemo.exadel.com/richfaces-demo/richfaces/stateAPI.jsf?c=stateAPI&tab=usage

                        4. State Manager API: http://livedemo.exadel.com/richfaces-demo/richfaces/stateAPI.jsf?c=stateAPI&tab=usage


                        I wish I would have integrated Seam at the beginning. It seems to be a lot of work afterwords..!?
                        I tried to use a4j:keepAlive but I got a lot of serialization exceptions. State Manager seems to be pretty complicated to me. Therefore I try to continue with the session beans.

                        Regards

                          <t:saveState value="#{timerepHandler.selectedDateStart} "/>
                          <t:saveState value="#{timerepHandler.selectedDateEnd} "/>
                          did the trick!!! No session beans necessary anymore!
