Update of /var/cvs/applications/taglib/src/org/mmbase/bridge/jsp/taglib
In directory james.mmbase.org:/tmp/cvs-serv6927
Modified Files:
ParamHandler.java ParamTag.java
Log Message:
Made it possible for ParamHandler tags, to accept params from inside a
sub-request (like a mm:include or a tagfile). At the moment supported by only
mm:link/mm:url, so that you can more easily make your own 'link' tags using
tag-files
