get value of HtmlSelectOneRadio

[James Ellis]

I have a strange situation where the components on a form are dynamically built and the form is submitted to an action method "create" on a Controller class. Basically the form looks like this:

HtmlPanelGrid
--HtmlOutputText
--HtmlPanelGrid
----HtmlSelectOneRadio
----HtmlInputText

(picture a table with 2 columns, the first is some text and the second contains a radio box and an input textbox)

Anyway, to do the validation on this page, in the action method I have code like this:

//Get the children of the main outer panelGrid
List children = htmlPanelGrid.getChildren();

Iterator it = children.iterator();
while (it.hasNext()) 
{
Object ob = it.next(); 
System.out.println("|"+ob.getClass().getName()+"|");

if(ob.getClass().getName().equals("javax.faces.component.html.HtmlPanelGrid"))
{
System.out.println("HtmlPanelGrid found");
 
HtmlPanelGrid nestedHtmlPanelGrid = (HtmlPanelGrid)ob;
//Get the children of the nested panelGrid
List panelGridChildren = nestedHtmlPanelGrid.getChildren();
 

Iterator pgIterator = panelGridChildren.iterator();
while (pgIterator.hasNext()) 
{
Object pgObj = pgIterator.next(); 
System.out.println("Panel Grid class found is "+pgObj.getClass().getName()+"");

//If a radio box is found, print it's value
if(pgObj.getClass().getName().equals("javax.faces.component.html.HtmlSelectOneRadio"))
{
HtmlSelectOneRadio htmlSelectOneRadio = (HtmlSelectOneRadio)pgObj;
System.out.println("htmlSelectOneRadio.getValue() "+htmlSelectOneRadio.getValue());
 
...
 

Unfortunately the htmlSelectOneRadio.getValue() call always returns null, regardless of whether or not the radio box is checked. How do I get the value of whether or not the radio box is checked? There is no isChecked method on that class...

PS - I can print out the id on that radio box and it is printing the correct ID, so I know that I at least have the correct component.

Since the full code of the managed bean and the corresponding JSP is not posted here,I think we can help you with debugging...

Please try setting up a phase listener and
see what's happening at each phase.

This seems to work:

  String radioButtonValue = request.getParameter(htmlSelectOneRadio.getId());
