rerender not working

sptexas May 23, 2009 9:42 AM

This may be a redundant post, but I don't understand why "PlotPanel" does not rerender, yet "StartDate" and "EndDate" work fine. "PlotPanel" is rendered correctly upon initialization, but never changes after that.

Note - "PlotPanel" works if I don't use binding.

<f:view>
 <body>
 <img src="images/DukeGuitar.jpg" class="floatLeft" height="82" width="96"/>
 <h1>#{dWRFD1.dWRFD1Title}</h1>
 <br clear="all" ></br>
 <table width="100%">
 <tr><td style="background-color: #200070" height="5"></td></tr>
 </table>
 <br clear="all" ></br>

<h:form id="EBOTForm">

 <h:panelGrid columns="6">
 <label for="PeriodRange">Previous:</label>

 <h:selectOneMenu id="PeriodRange" value="#{dWRFD1Handler.range}" required="true">
 <f:selectItems value="#{dWRFD1Handler.ranges}" />
 <a4j:support event="onchange" reRender="PlotPanel, StartDate, EndDate" />
 </h:selectOneMenu>

 <label for="StartDate" >Start:</label>
 <h:outputText id="StartDate" value="#{dWRFD1Handler.startDate}" >
 <f:convertDateTime type="date" pattern="MM/dd/yy h a" />
 </h:outputText>

 <label for="EndDate" >End:</label>
 <h:outputText id="EndDate" value="#{dWRFD1Handler.endDate}">
 <f:convertDateTime type="date" pattern="MM/dd/yy h a" />
 </h:outputText>

 <h:commandButton id="downloadBTN" value="download" action="#{dWRFD1Handler.act}" style="width: 6em" />

 </h:panelGrid>

 <rich:tabPanel id="PlotPanel" binding="#{dWRFD1Handler.tabPanel}" width="85%">
 </rich:tabPanel>

</h:form>

</body>
</f:view>

After reading some more on problems similar to this, I tried wrapping the TabPanel in an <a4j:outputPanel>, but the "PlotPanel" still does not render, but the "StartDate1" does rerender within the panel.

Any ideas as to what I'm missing here would be greatly appreciated.

 <h:form id="EBOTForm">

 <h:panelGrid columns="6">
 <label for="PeriodRange">Previous:</label>

 <h:selectOneMenu id="PeriodRange" value="#{dWRFD1Handler.range}" required="true">
 <f:selectItems value="#{dWRFD1Handler.ranges}" />
 <a4j:support event="onchange" reRender="PlotPanel, StartDate, EndDate" />
 </h:selectOneMenu>

 <label for="StartDate" >Start:</label>
 <h:outputText id="StartDate" value="#{dWRFD1Handler.startDate}" >
 <f:convertDateTime type="date" pattern="MM/dd/yy h a" />
 </h:outputText>

 <label for="EndDate" >End:</label>
 <h:outputText id="EndDate" value="#{dWRFD1Handler.endDate}">
 <f:convertDateTime type="date" pattern="MM/dd/yy h a" />
 </h:outputText>

 <h:commandButton id="downloadBTN" value="download" action="#{dWRFD1Handler.act}" style="width: 6em" />

 </h:panelGrid>

 <a4j:outputPanel layout="block">
 <a4j:outputPanel ajaxRendered="true">
 <rich:tabPanel id="PlotPanel" binding="#{dWRFD1Handler.tabPanel}" width="85%" renedered="true">
 </rich:tabPanel>
 <label for="StartDate1" >Start:</label>
 <h:outputText id="StartDate1" value="#{dWRFD1Handler.startDate}" >
 <f:convertDateTime type="date" pattern="MM/dd/yy h a" />
 </h:outputText>
 <h:messages/>
 </a4j:outputPanel>
 </a4j:outputPanel>

 </h:form>

 public HtmlTabPanel getTabPanel() {
 LOG.info("getTabPanel()");
 FacesContext context = FacesContext.getCurrentInstance();
 Application application = context.getApplication();
 tabPanel = (HtmlTabPanel) application.createComponent(HtmlTabPanel.COMPONENT_TYPE);

 for (Well well : getWells()) {
 HtmlTab tab = (HtmlTab) application.createComponent(HtmlTab.COMPONENT_TYPE);
 tab.setId("well_" + COUNTER);
 tab.setLabel(well.getName());
 HtmlGraphicImage graphicImage = (HtmlGraphicImage) application.createComponent(HtmlGraphicImage.COMPONENT_TYPE);
 graphicImage.setId("image_" + COUNTER++);
 String plotURL = getPlot(well);
 graphicImage.setUrl(plotURL);
 tab.getChildren().add(graphicImage);
 tabPanel.getChildren().add(tab);
 }
 return tabPanel;
 }

binding should be request scoped.
