Exception with selectManyCheckBox inside dataTable

[Martin Peřina]

Hello,

I tried to use a checkbox on each row of a dataTable using
this minimalized JSP code:

    <t:dataTable cellspacing="0" frame="border" rules="rows"
        value="#{selectManyCheckboxBean.items}"
        var="item" rowIndexVar="rowIndex">

      <h:column>
        <f:facet name="header">
          <t:selectManyCheckbox id="selectManyCheckbox" layout="spread">
            <f:selectItems value="#{selectManyCheckboxBean.items}" />
          </t:selectManyCheckbox>
          <h:outputText value="Selected" />
        </f:facet>

        <t:checkbox for="selectManyCheckbox" index="#{rowIndex}"/>
      </h:column>

      ...

    </t:dataTable>


Backing bean code:

public class SelectManyCheckboxBean {
    private List items;
    private String[] selectedItems;

    public SelectManyCheckboxBean() {
        setItems(new ArrayList());
        getItems().add(new SelectItem("Item 1"));
        getItems().add(new SelectItem("Item 2"));
        getItems().add(new SelectItem("Item 3"));
    }
    
    public List getItems() {
        return items;
    }

    public void setItems(List items) {
        this.items = items;
    }

    public String[] getSelectedItems() {
        return selectedItems;
    }

    public void setSelectedItems(String[] selectedItems) {
        this.selectedItems = selectedItems;
    }
...
}


When the page is accessed, this exception is thrown:
