Component ID .... has already been found in the view with t:dataScroller.

[Chandan Rajan]

Hi,

I am attempting to use the paged, sortable table using Tomahawk's t:dataScroller. I am deploying this in Glassfish app server inside a portlet.

When I first view the page, there are no issues, the table is rendered properly. After the first rendering, if I refresh the page, it throws the following exception:

"java.lang.IllegalStateException: Component ID j_id_id8:studentScrollfirst has already been found in the view. See below for details...."

My JSP page looks like the follows:

    
<t:dataTable
id="studentTable" 
value='#{department.students}' 
            var="student"
            border="0" 
            rows="5"
            styleClass="liferay-table taglib-search-iterator" 
            rowClasses="portlet-section-alternate,portlet-section-body"
            sortColumn="#{department.sortColumn}"
            sortable="true" >            
            <t:column defaultSorted="true">
                <f:facet name="header">
                <t:commandSortHeader columnName="ID" arrow="true">
                    <h:outputText value="#{msgs.IdColumnHeader}"/>
                    </t:commandSortHeader>
                </f:facet>
                <h:outputText value="#{student.Id}" />
            </t:column>
            <t:column>
                <f:facet name="header">
                <t:commandSortHeader columnName="name" arrow="true">                
                    <h:outputText value="#{msgs.nameColumnHeader}"/>
                    </t:commandSortHeader>
                </f:facet>
                <h:outputText value="#{student.name}" />
            </t:column>
...
        </t:dataTable>
 
    <h:panelGrid columns="1" styleClass="scrollerTable2" columnClasses="standardTable_ColumnCentered" >
        <t:dataScroller id="studentScroll"
                        for="studentTable"
                        fastStep="10"
                        pageCountVar="pageCount"
                        pageIndexVar="pageIndex"
                        styleClass="scroller"
                        paginator="true"
                        paginatorMaxPages="9"
                        paginatorTableClass="paginator"
                        paginatorActiveColumnStyle="font-weight:bold;">            
            <f:facet name="first" >
            <h:outputText id="firstLink" value="First"/>                
            </f:facet>
            <f:facet name="last">
                <h:outputText id="lastLink" value="Last"/>
            </f:facet>
            <f:facet name="previous">
                <h:outputText id="previousLink" value="Previous"/>
            </f:facet>
            <f:facet name="next">
                <h:outputText id="nextLink" value="Next"/>
            </f:facet>
        </t:dataScroller>
    </h:panelGrid>        
 

department managed bean is configured as following in faces-config.xml:

    
    <managed-bean>
        <managed-bean-name>department</managed-bean-name>
        <managed-bean-class>xyz.abc.Department</managed-bean-class>
        <managed-bean-scope>session</managed-bean-scope>        
    </managed-bean>

Am I missing something?

Thanks,
Chandan

Hi,

I have exactly the same problem. I can not find out what the reason is.
It seems when I remove some elements the page works fine, but after I added some more elements I run again in the problem.
I updated all my JSF Libaries. Now I am using:

myfaces-api 1.2.3
myfaces-impl 1.2.3
tomahawk 1.1.6
jsf-facelets 1.1.14
