Exception with selectManyCheckBox inside dataTable
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:

Thanks, that was the problem.

This may not be your only problem, but it's one.
You may only have one child component in the facet tag.
Wrap your two components inside of a <h:panelGroup>
<f:facet name="header">
<h:panelGroup>
<t:selectManyCheckbox id="selectManyCheckbox" layout="spread">
<f:selectItems value="#{selectManyCheckboxBean.items}" />
</t:selectManyCheckbox>
<h:outputText value="Selected" />
</h:panelGroup>
</f:facet>
