Hello,

Is there anyway for a tree to support an empty message in case it has no results? Both grid and listbox support an empty message. And we need to use a tree with trecols to show a list that has several levels of categories, but if the model of the tree is empty because there are no results (I.e. By doing a search of the elements of the tree) we wanted to have an empty message like there is on a grid or a listbox.

I created a fiddle to show an empty tree: zkfiddle.org/sample/3inton9/1-Empty-Tree

The zul of that fiddle is this:

<zk>
    <window id="uploadVideo"
            apply="org.zkoss.bind.BindComposer"
            viewModel="@id('vm') @init('pkg$.TestVM')">
        <tree model="@load(vm.model)">
                    <treecols>
                          <treecol label="Item"/>
                    </treecols>
        </tree>
    </window>
</zk>
