Hi Andy, thanks for your reply. I am binding to a
String in
<h:selectOneRadio
value="#{dataManagementBean.dataTransferTypeItems[0]}"
........>
The dataTransferTypeItems[0] is a String.
Actually, I have two radio buttons. One stands for
"import" and the other stands for "export". I am
trying to set a default radio button to "import"
What should I do to fix the problem? Thanks for
guidance in advance.
