Richard,
Thank you for the response! Unfortunately it is a little unclear to me.
Where would that snippet go? The layoutWithMenu.jsp page? If so, that
still forces me to specify the default value(s) in both layout.jsp and
layoutWithMenu.jsp...which is what I'm really trying to avoid.
I would like to make these layout-components as pass-through components
(pageA.jsp --> layoutWithMenu.jsp --> layout.jsp), but when nothing is
specified/overridden then use the default values from the master
layout.jsp template.
Oh, and just to clean things up, the layout.jsp in my original post is
missing it's html-head section, it should be:
<head><title>${title}</title></head>

Re: [Stripes-users] Using both default values and overridden values within
nested layouts?
Hi Chris,
what about
<c:if test="${empty header}">
<c:set var="header">Default Header</c:set>
</c:if>
?
