Unwanted Validation

Now there is an unwanted validation error message when the user simply selects a different country from the list.

Recall that the select menu does a submit when there is a menu change:

     <h:selectOneMenu value="#{form.country}" onchange="submit()"
        valueChangeListener="#{form.countryChanged}">
        <f:selectItems value="#{form.countryNames}"/>
     </h:selectOneMenu>

Then the Process Validations phase of the JSF life cycle catches the validation error.

Note that the first process events phase has an option to bypass validation and go directly to the Render Response phase.

This is accomplished by:

• Making the select menu an immediate input component, and

• Having the change listener call the FacesContext.renderResponse method.
