ui:repeat JSF 2.0 cannot render iterate p:row primefaces

Question

I got a problem here, my system config was Mojarra 2.1.7, Primefaces 3.2 and using Glassfish 3.1+.

before this, i got my code well rendered using this codes:

<p:tabView>
    <p:tab title="Offices Access" >
         <h:outputText value="Access | Offices Name | Offices Code | Parent Offices" style="font-weight: bold;"/>

         <ui:repeat value="#{userBean.officeses}" var="office">
              <h:panelGrid columns="2">
                   <p:selectBooleanCheckbox id="access#{office.officesID}" style="width: 50px;"/>
                   <h:outputLabel for="access#{office.officesID}" value="#{office.officesName} | #{office.officesCode} | #{office.parentOffices}"/>
               </h:panelGrid>
         </ui:repeat>
     </p:tab>
</p:tabView>

and i find this is generate rather ugly interfaces, so i ran over p:panelGrid from primefaces.
after i write some code and from my expectation it would work, but it DONT :(
this code render the header perfectly, but right after the ui:repeat code, it wouldnt render the p:row and the p:column inside it.

here is the code :

<p:tabView>
    <p:tab title="Offices Access" >
        <p:panelGrid styleClass="centerContent">
             <f:facet name="header">
                 <p:row>
                     <p:column style="font-weight: bold;">Access</p:column>
                     <p:column style="font-weight: bold;">Offices Name</p:column>
                     <p:column style="font-weight: bold;">Offices Code</p:column>
                     <p:column style="font-weight: bold;">Above Level Offices</p:column>
                 </p:row>
            </f:facet>

            <ui:repeat value="#{userBean.officeses}" var="office">
                <p:row id="rowforOffice#{office.officesID}">
                    <p:column><p:selectBooleanCheckbox id="access#{office.officesID}"/></p:column>
                    <p:column><h:outputText value="#{office.officesName}"/></p:column>
                    <p:column><h:outputText value="#{office.officesCode}"/></p:column>
                    <p:column><h:outputText value="#{office.parentOffices}"/></p:column>
                </p:row>
            </ui:repeat>
       </p:panelGrid>
    </p:tab>
</p:tabView>

am i miss something..?
or it is was a bug..? because i ran over google looking for this kind of code and i found nothing.

know that: you can't assign ids inside `ui:repeat` like this `id="someText#{someBean.someThing}"` instead just do `id="someText"` and it will be suffixed with unique enumeration — Daniel, May 23 '12 at 12:04
humm, thanks.. :D that will improve my knowledge.. :D but removing the `id="someText#{someBean.someThing}"` still doesnt resolve the problem.. any tehcnique that i can do to resolve this ? — Wirawan Adi, May 24 '12 at 01:42
Try to replace `ui:repeat` by another repeater , start with ` — Daniel, May 24 '12 at 05:48
I ran into exactly the same problem and wasted a good half hour trying to figure this out. Very strange — Gaurav Sharma, Oct 23 '12 at 14:44

As to the concrete problem, the <ui:repeat> is a view render time tag. Thus, it's physically present in the JSF component tree and generates its HTML output as many times as it needs to iterate over the value.

However, the <p:panelGrid> expects physically multiple <p:row> or <p:column> children, not a single <ui:repeat> with therein a single <p:row>. In other words, they needs to be prepared during the view build time instead of the view render time.

The JSTL <c:forEach> is a view build time tag. It will generate physically multiple <p:row> components into the JSF component tree and hence the <p:panelGrid> will find solely <p:row> children.

<p:panelGrid styleClass="centerContent">
    <c:forEach items="#{userBean.officeses}" var="office">
        <p:row id="rowforOffice#{office.officesID}">
            <p:column><p:selectBooleanCheckbox id="access#{office.officesID}"/></p:column>
            <p:column><h:outputText value="#{office.officesName}"/></p:column>
            <p:column><h:outputText value="#{office.officesCode}"/></p:column>
            <p:column><h:outputText value="#{office.parentOffices}"/></p:column>
        </p:row>
    </c:forEach>
</p:panelGrid>

Note: this breaks view scoped beans in Mojarra versions older than 2.1.18. If you can't upgrade, then consider a <p:dataTable> instead, as you already found out yourself.

<p:tabView id="tabCustomerView">
    <p:tab title="Fasilitas Nasabah">
                <p:fieldset legend="Detil Fasilitas">
                    <p:dataTable value="#{custViewBean.customerSavingAccounts}"
                                 var="customerSavingAccount"
                                 rowIndexVar="customerSavingAccountRowIndex"
                                 paginator="true"
                                 paginatorTemplate="{CurrentPageReport} {FirstPageLink} {PreviousPageLink} {PageLinks} {NextPageLink} {LastPageLink} {RowsPerPageDropdown}"
                                 rows="10"
                                 rowsPerPageTemplate="5,10,15"
                                 paginatorPosition="top">

                        <p:column headerText="Jumlah Pembayaran">

                        </p:column>

                        <p:column headerText="Status">

                        </p:column>
                    </p:dataTable>
                </p:fieldset>
            </p:tab>
</p:tabView>

So, use datatable for nicer looks to display your datas :) Have fun.
