IncludeTransformer does not handle multi-valued parameters
----------------------------------------------------------
Key: COCOON-2298
URL: https://issues.apache.org/jira/browse/COCOON-2298
Project: Cocoon
Issue Type: Bug
Components: * Cocoon Core
Affects Versions: 2.1.11
Reporter: Nico Verwer
When you pass multivalued parameters to
org.apache.cocoon.transformation.IncludeTransformer, like:
<ci:parameter name="foo" value="bar"/>
<ci:parameter name="foo" value="baz"/>
only the last gets passed in the request made by IncludeTransformer. This is
because parameters are stored in a Map.
HTTP specifies that multi-valued parameters are possible, or rather it does not
forbid them. So the query-string "?foo=bar&foo=baz" is perfectly legal.
The patch changes the way IncludeTransformer handles this case, so that
multi-valued parameters are handled correctly. The NetUtils.parameterize()
method, used by IncludeTransformer, was already prepared for this.
