[web] Templates nesting/includes
--------------------------------
Key: LABS-241
URL: https://issues.apache.org/jira/browse/LABS-241
Project: Labs
Issue Type: New Feature
Components: Magma
Affects Versions: Current
Reporter: Simone Gianni
Assignee: Simone Gianni
Fix For: Future
While it is possible to extend a template class with another template class,
and inherit/override as usual, this is not currently possible on an HTML level.
That means that a web site will have a TempateA.java and a TemplateA.html. Then
a TemplateB.java, extending TemplateA and simply overriding and cutomizing
stuff, but must have a TemplateB.html file (if needed) that must redefine
everything that was in TemplateA.html.
It would be nice to have a TemplateB.html that simply "patches" TemplateA, but
unfortunately this is not so easy, because there is no known standard on
patching an HTML file. XSLT could be a way, but that would be rather an
extension than a new feature.
Instead, this lack can be mitigated having a way to include a template in
another template. This way, common parts between TemplateA and TemplateB could
be refactored out in, say, FooterTemplate, HeaderTemplate and so on.
We still need to investigate wether this kind of inclusion should be done in
the java class, using the current layout system, and/or in HTML directly.
