    <tree model="@load(vm.treeModel)" rows="10"  multiple="true" checkmark="true">

There are only radio boxes, not multiple boxes.

when using a TreeModel the model takes precedence over component properties. I assume you are using DefaultTreeModel, which implements the Selectable interface (including the Selectable.isMultiple() method). If that's the case then you simply have to call treeModel.setMultiple(true) in your viewModel and tree will enable multiple selection (handled by the TreeModel).

You can further remove the multiple="true" attribute in your zul code, since it's overridden by the TreeModel anyway.
