JSF Validation message not displaying in template's content part - html

Question

I got problem with non displaying validation error message on my form, when I'm using templates.
It does validation ok, as I can see I am not forwarded to next page, but I dont see error message.
When I try same code without defining layout template parts it prints message.
This is my form code:
<h:form>
<h:panelGrid columns="2">
<h:outputLabel for="mname">Username </h:outputLabel>
<h:inputText required="true" requiredMessage="Username is required.">
</h:inputText>
<h:commandButton value="Submit"></h:commandButton>
</h:panelGrid>
</h:form>
And this is my code when I'm defining content part:
<!-- Content -->
<ui:define name="content">
<h:form>
<h:panelGrid columns="2">
<h:outputLabel for="mname">Username </h:outputLabel>
<h:inputText required="true" requiredMessage="Username is required.">
</h:inputText>
<h:commandButton value="Submit"></h:commandButton>
</h:panelGrid>
</h:form>
</ui:define>
Anyone got reason why wouldn't I see error message when I'm defining my layout page.
This is my layout.xhtml content part.
<div id="content">
<ui:insert name="content">
<ui:include src="/template/content.xhtml" />
</ui:insert>
</div>

Eventually you will need a h:message tag.. the requiredMessage is a tip for the framework on what to print in the message tag.
So you should have a set up like:
<h:form>
<h:message showSummary="true" showDetail="false"
id="errorsMessages"
for="txt"/>
<h:panelGrid columns="2">
<h:outputLabel for="mname">Username </h:outputLabel>
<h:inputText id="txt" required="true" requiredMessage="Username is required.">
</h:inputText>
<h:commandButton value="Submit"></h:commandButton>
</h:panelGrid>
</h:form>
