<rich:tree> with checkboxes?

[viggo.navarsete]

Hi,

i need a tree with checkboxes next to each node in the tree, so that I'm able to select/deselect each node in the tree. Does it exist already, or is it possible to extend the existing tree to do it?

You may have anything you need in a tree model, or use built-in selection model in tree.

Thanks for your repy ishabalov:)

Do you have any examples on exactly _how_ to do that? I'm pretty new to JSF in general, and Richfaces.

A possible solution is this:
- keep a 'Map<Object,Boolean> selected' in the sessionbean. 'Object' is the data of the treenode.
- expose the map in the interface of the SB
- refer to the the map in the template:

 <rich:tree value="#{bean.tree}" var="data" >
 <rich:treeNode>
 <h:selectBooleanCheckbox value="#{mybean.selection[data]}"/>${data.name}
 </rich:treeNode>
 </rich:tree>

Name("mybean")
@Stateful
@Scope(ScopeType.CONVERSATION)
public class TestMaintenanceBean implements TestMaintenance {
 private Map<Object, Boolean> selection=new HashMap<Object,Boolean>();

 public Map<Object, Boolean> getSelection() {
 return selection;
 }

}

The Map will contain your 'data' as the key and a Boolean value 'true' for selected nodes (and false for de-selected nodes, or no entry if not selected).

I forgot: this is with seam, but should work with plain JSF as well

Thanks evdelst for your input!

I think I will try to use the Tomahawk tree, like discussed in this thread:
