My Netbeans gives me some messages. Maybe it might help you to get an ideas.
When added an id to HTML Form tag and
JSF message for form id I started getting some messages in Netbeans.
Here are my HTML FORM details:
<form id="submitForm">
.
.
.
<td><h:inputText value="#{ServicesBean.serviceName}" id="serviceName" size="50"/></td>
.
.
.
<h:commandButton action="#{ServicesBean.addService}" value="#{bundle.addNewlySoldServiceButtonValue}" id="submitButton"/>
</form>
<h:message for="submitForm"/>
Here are NetBeans Messages:
