Want a Default Selected Radio Button. What to Do?

[Caroline Jen <ji...@yahoo.com>]

I want to show a default selected radio button when
the web page is loaded for the first time.  Normally,
I create a set of radio buttons this way:

[code]
<h:selectOneRadio
value="#{dataManagementBean.dataTransferType}"
layout="pageDirection" >
     <f:selectItems
value="#{dataManagementBean.dataTransferTypeItems}"/>
</h:selectOneRadio>
[/code]

To show a default selection, I can add a statement in
my backing bean
 
[code]
String defaultSelectedDataTransferType =
"imports";[/code] 
where "imports" is the value of one of my buttons. 
Then, I display the web page this way:

[code]
<h:selectOneRadio
value="#{dataManagementBean.defaultSelectedDataTransferType}"
layout="pageDirection" >
     <f:selectItems
value="#{dataManagementBean.dataTransferTypeItems}"/>
</h:selectOneRadio>
[/code]

The problem is that whatever the radio button that
users actually select, its value is assigned to the
[b]defaultSelectedDataTransferType[/b].

I want the [b]dataTransferType[/b] gets the value of
the button that users select.  What should I do?

put the default value into the inital value of dataTransferType:

String _dataTransferType = DEFAULT_VALUE;

public String getDataTransferType()
{
  return _dataTransferType;
}

public void setDataTransferType(String value)
{
  _dataTransferType = value;
}
