Hi All,
I've just revamped my RequestParamMatcher by turning it into an
action, and making it store all request parameters for use in the
sitemap, as opposed to specifying the parameter as previously
implemented.
Attached is the new source file (which can replace the
RequestParamMatcher completely, it's compatible with it), and a patch
to the webapp showing an example. Limited docs are in the javadoc
comments.
I've also added the locale action definition to the webapp (forgot to
do it in my previous email), and fixed up the locale action's author
tags for the docs (sorry Lassi/Konstantin! :-) )
I've had thoughts about extending the RequestParamAction so that it
can operate not just with request parameters, but also with
session values, context values, etc. Is there be interest out there
in having such functionality ?
Cheers, hope everyone has a great weekend.
Marcus
