Facelets: need only an <ui:define> tag of a page
Okay, to include a page in another page I need <ui:include src="pageName"/> tag. But if i want to include only a portion of a page?
Let me explain:
I have a template that has the tag <ui:insert name="body"/> and other <ui:insert.../> tags.
A page, List.xhtml, uses this template and, of course, fills up ALL the template tags. Now, in another page, named Create.xhtml (that uses the same template), at a certain point, i want to put ONLY the body tag cont开发者_开发百科ent of List.xhtml, not other tags. Is it possible?
Thank you for you answers.
Easiest might be to break out the body section of your List.xhtml into its own <ui:composition>. Then you can re-use it in with <ui:decorate> in the pages where you need it. This would be the "template" way of doing it.
Alternativly, you can create a <ui:component> out of the body section. This would be the "component" way of doing it. Both should achieve the same basic goal you have, but composition/decorate might be simpler.
UPDATE Example (See also here).
commonBody.xhtml
...
<ui:composition>
<p>This is some common body.</p>
<p><ui:insert name="dynamicBody" /></p>
</ui:composition>
List.xhtml
...
<body>
<h1>This is the List.xhtml</h1>
<ui:decorate template="commonBody.xhtml">
<ui:define name="dynamicBody">Body of List.xhtml</ui:define>
</ui:decorate>
</body>
...
Would output something like
...
<body>
<h1>This is the List.xhtml</h1>
<p>This is some common body.</p>
<p>Body of List.xhtml</p>
</body>
...
Another way:
template.xhtml:
......
<ui:insert name="body"/>
......
List.xhtml:
<ui:composition xmlns=....... template="/template.xhtml">
..............
<ui:define name="body">
<ui:include src="ListContent.xhtml"/>
</ui:define>
..............
</ui:composition>
ListContent.xhtml
<ui:component xmlns....>
Content I can reuse in other pages different by List.xhtml
(without see List.xhtml entire content, which is the scope of this question),
simply writing "<ui:include src="ListContent.xhtml"/>" in the target page code.
</ui:component>
Hope can help someone.
