Hi! There's a use case where I encounter a problem with my solution. When a validation error occurs in the process validations phase, all the radio buttons shown in the HtmlDataTable aren't rendered when the page is redisplayed.
Why I try to evaluate the HtmlSelectOneRadio components in this view state, I get a runtime error because the components aren't fully initialized. The component values / value classes are of the following type, for example: value = [EMAIL PROTECTED] value class = org.apache.myfaces.renderkit.RendererUtils$1 Do you know how this can be prevented?
