Hi. I'm having some problems using the tomahawk datascroller inside a portlet in GateIn portal. Details of portal versions,code snippets, and error messages are below.

Note: Without the datascroller code in the JSP, the datatable  displayed correctly. When the datascroller is in the JSP file, the error  message "

Has anyone used tomahawk libraries in GateIn portal successfully? Your help in solving this problem is appreciated.

---------------Problem details----------------

GateIn portal version: 3.0.1

Tomahawk version: (1.1.10 for JSF 1.2)

Portlet Bridge version : 2.0.0

Code in JSP page:

<%@ taglib uri="http://java.sun.com/jsf/html" prefix="h"%>
<%@ taglib uri="http://java.sun.com/jsf/core" prefix="f"%>
<%@ taglib uri="http://myfaces.apache.org/tomahawk"  prefix="t"%>

<f:view>

<h:message showSummary="true" showDetail="false" style="color: red; font-weight: bold;" for="name" />

<h:form id="helloForm">

<t:dataTable rendered="true" id="data" styleClass="tableData" value="#{myBackingBean.events}"
             var="ev" rows="#{myBackingBean.rowsperpage}">

            <h:column rendered="true">
            <h:outputText value="#{ev.eventName}"/>
            </h:column>
       
        </t:dataTable>
       
       
<div>
<t:dataScroller id="scroller" for="data" paginator="false"
                         fastStep="2" paginatorMaxPages="100"
                         paginatorActiveColumnStyle="font-size:20px;font-weight:bold;"
                         immediate="true"
                         pageCountVar="pageCount"
                         pageIndexVar="pageIndex"
                         firstRowIndexVar="firstRowIndex"
                         lastRowIndexVar="lastRowIndex"
                         rowsCountVar="rowsCount"
                         displayedRowsCountVar="displayedRowsCount">
             <f:facet name="previous">
               <h:panelGroup rendered="#{pageIndex!=1}">
               <t:outputText value="#{labels['DataScroller_Previous']}"/>
                </h:panelGroup>
            </f:facet>
            <f:facet name="next">
              <h:panelGroup rendered="#{pageIndex < pageCount}">
               <t:outputText value="#{labels['DataScroller_Next']}"/>
                </h:panelGroup>
            </f:facet>
        
       
         </t:dataScroller>
     </div>

-------------------

Backing Bean java code:

private ArrayList<EventDetails> events;

public ArrayList<EventDetails> getEvents() {
        return events;
    }

    public void setEvents(ArrayList<EventDetails> events) {
        this.events = events;
    }

An xml string is retrieved from the database, parsed, and formed items added to the ArrayList of EventDetails. (EventDetails is another java class containing data members and their corresponding getters and setters).
