Mixing plain HTML and JSF-Tags
Hi Gerald,

Sure, it would be nice to have jsf pages without plain html.
But in reallity this wouldn't happen:
In 90% of the projects I know, HTML is delivered from web-designer experts.
Those people don't know about JSF and components. And I think they
don't have to.
In real projects this HTML is taken as the view component and the
developer enhances the view with bean values and some navigation
rules.
But it isn't practical to force the developer to remap all the HTML
into JSF components (and for complex HTML this doesn't really work).
When looking at JSF example-applications I always see mixing of plain
html and JSF components. It works for f:view.
The question is: Why doesn't it work for f:subview? Is there a
workaround without wrapping anything in jsf-tags or using facelets?
Greetings

Re: Mixing plain HTML and JSF-Tags

You may be in the market for facelets. See the following...
https://facelets.dev.java.net/nonav/docs/dev/docbook.html#taglib-use-jsfc
It is possible to map simple input elements to jsf ui objects, but keeping
standard html syntax. I haven't personally used this, and I assume it
wouldn't work for more complex objects, but its something to look at.
You might be able to use composition in facelets for more complex
situations. For example, lets say you wanted a table in the page. I don't
imagine the table tag and the panelGrid objects play well together with the
jsfc attribute, but you could have the following on the page...
<html xmlns:h="http://java.sun.com/jsf/html" xmlns:f="
http://java.sun.com/jsf/core">
(etc)...
<ui:insert name="customTable">
<table>
<tr><td>This is a sample name</td><td><input type="text"
value="This is a sample input object"/></td></tr>
</table>
</ui:insert>
(more fluff)...
</html>
This could be on the "template" version of the page that a designer would
create. You'd have to train them to work around the 'ui:insert' tag. But I
think that would be it. The "real" page would just be...
<html xmlns:h="http://java.sun.com/jsf/html" xmlns:f="
http://java.sun.com/jsf/core">
<ui:composition template="[point to template above]">
<ui:define name="customTable">
<h:panelGrid width="100%" columns="2">
<h:panelGroup>
NOT a sample name
</h:panelGroup>
<h:panelGroup>
<h:inputText value="NOT a sample value"/>
</h:panelGroup>
</ui:define>
</ui:composition>
</html>
