I've never used Layout, I've always used Tag Files. I'm a Tag File zealot. They're simply too simple and too
powerful to make be bother to look anywhere else. Tag files give JSP a refactorability and elegance I
haven't found really in any other markup solution.

Re: Layout reuse "like a component"

With a layout, a "parameter" can consist of a large block of JSP.
Like, the page body, or a large fraction of it, or a dialog body, or
page navigation block. There can be any number of such parameters.

You can do that with a Java-coded tag but not a tag file, other than
the single "body".

That said, I like tags too

Re: Layout reuse "like a component"

As far as I understood the example at
http://stackoverflow.com/questions/1296235/jsp-tricks-to-make-templating-easier/3257426#3257426,
you can actually do it:

<%@tag description="User Page template" pageEncoding="UTF-8"%>
<%@taglib prefix="t" tagdir="/WEB-INF/tags" %>
<%@attribute name="userName" required="true"%>

<t:genericpage>
    <jsp:attribute name="header">
      <h1>Welcome ${userName}</h1>
    </jsp:attribute>
    <jsp:attribute name="footer">
      <p id="copyright">Copyright 1927, Future Bits When There Be Bits Inc.</p>
    </jsp:attribute>
    <jsp:body>
        <jsp:doBody/>
    </jsp:body>
</t:genericpage>

Here, you pass JSP fragements encapsulated in jsp:attribute. I didn't
try that myself, though.

OK awesome.  I'll see about trying the snapshot.

Checkboxes

Can someone explain exactly when checkboxes are rendered checked.. 
I've done some playing around but it's still unclear to me how exactly
they should work:

<stripes:checkbox name="item.id" value="A" checked="A"/> not checked ?
<stripes:checkbox name="item.id" value="A" checked="B"/> not checked ?

The documentation says:  If the value of the checkbox is found to equal or be 
contained by the 'checked' object then the checkbox will default to
rendering as checked.

I find that if the value of the checkbox is found to be 
equal to the value in name then the checkbox is checked..

Can someone explain how i should be using this ? 

Thanks,
..Chris
