When the variable name of a template matches a viewmodel property name, there may be a stackoverflow when the content of that property changes.

Zul:

<zk xmlns="http://www.zkoss.org/2005/zul">
<div apply="org.zkoss.bind.BindComposer" viewModel="@id('vm') @init('test.TestViewModel')" >
<template name='tmplt'>
<selectbox model="@bind" selectedItem="@bind(selected)">
<template name='model'>
<label value='${each}' />
</template>
</selectbox>
</template>
<apply template='tmplt' x="@load(vm.model)" selected="@ref(vm.selected)"/>
<label value="@load(vm.selected)" />
</div>
</zk>

ViewModel:

package test;
public class TestViewModel {

List<String> model = new LinkedList<String>();
private String selected;

@Init
private void init()

Unknown macro: { model.add("1"); model.add("2"); model.add("3"); model.add("4"); model.add("5"); }

public ListModelList<String> getModel()

Unknown macro: { return new ListModelList(model); }

public String getSelected()

Unknown macro: { return selected; }

public void setSelected(String selected)

Unknown macro: { this.selected=selected; }

}

Try to change the value of the selectbox and you will get the following error:
