Hi

The problem in the below code is even though i set checkmark = true and multiple = true, but still shows like radio button only. i,e single selection.
I want to make as per the demo
http://www.zkoss.org/zkdemo/tree/multiple_selection


Here is the code.

Zul File

<?init class="org.zkoss.zkplus.databind.AnnotateDataBinderInit"?>
<zk>
<div id="treeDiv" apply="mypack.TreeComposer">
  <label id="lbl" />
    <tree id="treeGrid" checkmark="true" multiple="true" width="550px" model="@{treeDiv$composer.treeModel}" treeitemRenderer="@{treeDiv$composer.treeRenderer}">
        <treecols>
            <treecol width="200px" label="Path" />
            <treecol width="350px" label="Description" />
        </treecols>
    </tree>
</div>
</zk>

If you use DefaultTreeModel, you must set the multiple flag in the model, not in the tree component:

public DefaultTreeModel<FileInfo> getTreeModel() {
  DefaultTreeModel<FileInfo> model = new DefaultTreeModel<FileInfo>(getFileInfoTreeData());
  model.setMultiple(true);
  return model;
}
