Nested layouts: allow enclosing layout-render tag to layout components within a
nested layout-definition (not just its own layout-definition)
---------------------------------------------------------------------------------------------------------------------------------------------
Key: STS-317
URL: http://mc4j.org/jira/browse/STS-317
Project: Stripes
Issue Type: Improvement
Components: Tag Library
Affects Versions: Release 1.4.2
Reporter: Philippe Laflamme
Assigned To: Tim Fennell
Attachments: layout-1.4.2.patch
I've hit a small but annoying limitation with nesting layout-definition tags.
Lets say I create a new layout-definition file (/layout/special.jsp) that
renders the /layout/default.jsp definition like so:
<layout-definition>
<layout-render name="/layout/default.jsp">
<layout-component name="contents">
<div id="imspecial">
${somethingSpecial} <%-- comming from a layout-component in enclosing
tag--%>
</div>
</layout-component>
</layout-render>
</layout-definition>
This works only in the situation where the enclosing tag only lays out the
"somethingSpecial" component. There is no way to override or layout any of the
"default.jsp" components such as header or footer.
My suggestion (and patch) is that when a layout-render tag is within a
layout-definition tag, the context of the layout-definition should override the
context of the layout-render tag. This would move layout-components and
parameters "downstream" into embedded layout-definitions until one of them
renders it. I find that it makes layout-definitions easier to "extend".
This might not find within the tags initial intent. If such an improvement is
not possible, I'd like to know what are the best-practices when nesting layouts
or event an alternative solutions to nesting...
