Re: Help with t:dataTable t:selectBooleanCheckBox

[Andrew Robinson <an...@gmail.com>]

You may want to try the control from Jenia. It is made to handle radio
and check boxes in a data table.

http://www.jenia.org/

Look under the dataTools "family"

You can then have something like:
XHTML:
<t:dataTable var="item" value="#{bean.items}">
  <t:column>
    <jdt:multipleRowsSelector selectionList="#{bean.selectedItems}" />
  </t:column>
</t:dataTable>

Java:
@Name("bean")
public class ExampleBean
{
  private List<Item> items = new ArrayList<Item>();
  private List<Item> selectedItems = new ArrayList<Item>();

  public List<Item> getItems() { return items; }
  public List<Item> getSelectedItems() { return selectedItems; }
  public void setSelectedItems(List<Item> selectedItems)
  { this.selectedItems = selectedItems; }
}
