<f:facet> not working with <h:form>

Question

I have a template, in which a <h:form> is defined. This <h:form> is used all over the application for the CRUD pages of entities.

So, at one place I need another enctype for the form, so that I can upload files. I thought I can solve this with a facet in the template:

<h:form id="main-form">
    <f:facet name="enctype">
        <ui:insert name="form-enctype"/>
    </f:facet>

    <ui:insert name="buttons"/><p/>
    <ui:insert name="content"/><p/>
    <ui:insert name="buttons"/>
    <ui:insert name="additionalHelper"/>

</h:form>

And at the concrete page I wanted to set the custom enctype this way:

<ui:define name="form-enctype">
    <h:outputText value="multipart/form-data"/>
</ui:define>

But in the source code I always end up with the default application/x-www-form-urlencodedas enctype for the <h:form>

Why is this happening? At other locations in the source code this is behaving properly.

Only elements that are specified to have facets have facets. You can't just make it up. – Anticipatory

The reference pages for h:form does not mention enctype facet. I don't think it is valid facet for h:form. However, there is attribute enctype.

If you want to define content type of the form in specific pages then use template parameters like shown below.

Template would look then:

<h:form id="main-form" enctype="#{myenctype}">

    <ui:insert name="buttons"/><p/>
    <ui:insert name="content"/><p/>
    <ui:insert name="buttons"/>
    <ui:insert name="additionalHelper"/>

</h:form>

and specific page has to define <ui:param name="myenctype" value="multipart/form-data"/>:

<ui:composition template="template.xhtml">
    <ui:param name="myenctype" value="multipart/form-data"/>
    <!-- other stuff like <ui:define ...> -->
</ui:composition>

If you want to provide default value for the parameter use ternary operator like described in this question.
