Hi, I have a simple testing page that test my PPR on a selectOneChoice component. when select a value from selectOnechoice 1, the selected value will display on a output label and also reset the selected value and the other selectOneChoice. However, it prints the selected values to the label correctly but it can't set the selected value for the other selectOneChoice. and

Here are my page and my value change event method.

<tr:form id="nhutForm">         
<tr:selectOneChoice id="one" value="#{nhutTestBean.one}" autoSubmit="true" immediate="true" valueChangeListener="#{nhutTestBean.onMyValueChanged}">
    <tr:selectItem label="0" value="0"/>
    <tr:selectItem label="1" value="1"/>
    <tr:selectItem label="2" value="2"/>
    <tr:selectItem label="3" value="3"/>
</tr:selectOneChoice>

<tr:selectOneChoice id="two" value="#{nhutTestBean.two}" partialTriggers="one">
    <f:selectItems value="#{nhutTestBean.myList}"/>
</tr:selectOneChoice>

<tr:outputText id="nhutTextBox" value="hello: #{nhutTestBean.output}" partialTriggers="one"/></tr:form>

and my valueChangeEvent method:

public void onMyValueChanged(ValueChangeEvent event) {
    this.setOutput((String)event.getNewValue());
    this.setTwo((String)event.getNewValue());
}

One thing I realize is that it calls my setTwo twice, the first the set the correct values, but the second time set it to null so that nothing would be selected for the two drop down box. please help. thank you so much.
