Try making it a property and using something like myAction.checkBox.

I'm not sure the _list.id resolves correctly as the list index.

Can't you e.g. decorate your entity with a selected boolean which you then connect the checkbox to? Then you can iterate through the list and see wich have been set...

shouldn't it read:

value="#{myList.chkbox[_list.id]}"

chkbox was outjected but I'm not sure it changes that much in this case...

Hmmm, but it isn't injected back(?)

Can you expand on this a little? I'd like to see if what you are suggesting can solve my current challenge with checkboxes and datatables.

Thanks,

There are probably better/cleaner ways to do it but I have used a sort of

  public class SelectedEntity {

    private boolean selected = false;

    private Entity entity;


    public SelectedEntity(Entity entity) {

      this.entity = entity;

    }

    ... setters / getters

  }

and then I return a List<SelectedEntity> to the datatable and bind the checkbox to var.selected and data to var.entity.entityproperty.

then when I perform an action I loop

for (SelectedEntity selectedEntity : list) {

  if (selectedEntity.isSelected) {

    doSomethingWith(selectedEntity.entity);

  }

}
