Hi Ravi,
Below is an example of how it can be done. I hope others can share their method as well.
JSPX Page:
<tr:selectOneChoice label="Select One"
                   valueChangeListener="#{backingBean.selectDdlSelectOne}"
                   autoSubmit="true" id="ddlSelectOne">
     <tr:selectItem label="Item One" value="one"/>
     <tr:selectItem label="Item Two" value="two"/>
     <tr:selectItem label="Item Three" value="three"/>
</tr:selectOneChoice>
<tr:inputText label="Input One"
                   binding="#{backingBean.txtInputOne}"
                   partialTriggers="ddlSelectOne"/>
     <tr:inputText label="Input Two"
                   binding="#{backingBean.txtInputTwo}"
                   partialTriggers="ddlSelectOne"/>Backing Bean:
public void selectDdlSelectOne(ValueChangeEvent valueChangeEvent) {
    // Add event code here...
    String newValue = (String)valueChangeEvent.getNewValue();
    formBean.getTxtInputOne().setValue("Text 1: " + newValue);
    formBean.getTxtInputTwo().setValue("Text 2: " + newValue);
}You need to set the autoSubmit to true and give the dropdownlist an ID. Then, set the partialTriggers to the dropdownlist's ID.
There are cases where you need to surround the inputTexts (or other elements you want to update) in a container (eg. panelGroupLayout) and set the partialTriggers at the container instead of the object itself.
