Simple question on SelectOneRadio

[Frederic Filiatrault]

Hi all,

Very simple question. Can you use int as itemValue for selectOneRadio? Or is it only String and we need to convert it?

For example :

  
<h:selectOneRadio id="mode" value="#{userForm.choice}">
     <f:selectItem itemValue="0" itemLabel="choice 0"/>
     <f:selectItem itemValue="1" itemLabel="choice 1"/>
     <f:selectItem itemValue="2" itemLabel="choice 2" />
     <f:selectItem itemValue="3" itemLabel="choice 3" />
</h:selectOneRadio>  
 

Of course, I have my Backing bean (UserForm.java) with a property int choice with getter/setter. ;)

Actually, it throws a misleading validation error saying "Value is not a valid option.". Was would be the best way to fix that? Thk!

You may use Integer type to add int values.
You may create a list of SelectItems with value as Integer & Label as String. You don't have to do any conversion then. The default conversion for Integer should handle this case. Moreover, the value for SelectItem should only be an Object and not a String.
