Here is my form:
<form action="j_security_check">
<h:panelGrid columns="2" bgcolor="#eff5fa" cellspacing="5" frame="box" styleClass="center">
<h:outputLabel value="User ID:"/>
<h:inputText id="j_username" tabindex="1" />
<h:outputLabel value="Password:"/>
<h:inputSecret id="j_password"/>
<h:outputLabel value=""/>
<h:commandButton id="login" value="Login"/>
</h:panelGrid>
</form>
It work fine with Glassfish 3.0.1, but since Glassfish 3.1 b2 it shows this warning as a FacesMessage
in the JSF page:
The form component needs to have a UIForm in its ancestry. Suggestion: enclose the necessary components within
<h:form>
If I change the <form action="j_security_check">
to <h:form>
, it does not fix it, I have to place the <h:form>
inside the <h:panelGrid>
.
This is just a Warning not an Error. Warnings are usually there to inform the developer about unforeseen situations/conditions which might not immediately cause technical errors/problems. Anything may just work flawlessly, but the behaviour/results may probably not be as the developer intented. A newbie developer may for example accidently have used <form>
instead of <h:form>
. Warnings like this are then helpful.
In your particular case, you are simply forced to use <form>
because of the need to submit to a non-JSF service. You as a more experienced developer know that it's legitimately valid. You can just ignore this warning. This warning will only appear when javax.faces.PROJECT_STAGE
is set to Development
anyway and not appear when it is set to Production
.
However, that it still displays the warning when there's another component like panelgrid in between the form and its input children, is a bug to me. I'd report it to the Mojarra guys. It look like as if it is checking the immediate parent only and not all of the parents. Update: it has been fixed as per Mojarra 2.1.3/2.2, see also issue 2147.
This is by the way not Glassfish specific. The newer GF version of course ships with a newer Mojarra version which has those warnings implemented. See also issue 1663.
