Refactor ViewPreparer support
-----------------------------
Key: SB-61
URL: http://issues.apache.org/struts/browse/SB-61
Project: Sandbox
Issue Type: Improvement
Components: Tiles
Affects Versions: 2.0
Environment: N/A (design issue)
Reporter: Antonio Petrelli
The "preparer" support in tags and definitions declared in Tiles definitions
configuration files consists of parsing "preparerClass" and "preparerUrl"
attributes.
Since "preparerUrl" is pretty useless, because it includes the URL in the
response and can be replaced by using the "template" attribute, it should be
removed.
Probably we should give support to "named preparers", i.e. preparers that are
defined in Tiles configuration files (maybe a "name-class" pair) and in a new
JSP tag. This way, tags can use preparers without instantiating a new one for
each JSP call: in this way, preparers configuration will resemble Struts action
configuration. If "named preparers" support will be implemented, probably
"preparerClass" attribute should be removed.
