Is it a best practices to wrap a h:form tag in the jsf template page

Question

<p><h:commandLink value="Apply Now" action="register" /></p>

when i writing code above, exception below throws:

[2/12/10 11:24:29:535 CST] 0000005f renderkit W Component j_id26 must be enclosed inside a form.

Is it a best practices to wrap a h:form tag in the jsf template page, and then every page using the template can just directly use the h:commandLink tag without hesitate on the h:form tag?

Answer 1

In my opinion <h:form> and <f:view> shouldn't be in the template page, because:

• you can't customize their attributes, like (notably: enctype or beforePhase)
• you may want multiple forms in a page.
• you may at some point, in some places need to replace <h:form> with <a4j:form> (for example)

If you have many, very simple pages, then you can make an alternative template, which includes the main template, and which adds <f:view> and <h:form>.
