[Patch] Parameters in blocks-protocol URIs get decoded too early
----------------------------------------------------------------

                 Key: COCOON-1943
                 URL: http://issues.apache.org/jira/browse/COCOON-1943
             Project: Cocoon
          Issue Type: Bug
          Components: - Blocks Framework
    Affects Versions: 2.2-dev (Current SVN)
            Reporter: Alexander Klimetschek


When you pass parameters in the query part of a block-protocol URI, eg. "block:super:/dosomething?param1=alpha&param2=beta",
and they include some encoded stuff, eg. "<br/>" encoded as "%3Cbr/%3E", this will get
decoded before the actual servlet request happens. This takes place in BlockConnection.parseBlockURI()
when uri.getSchemeSpecificPart() is called, which will decode the string. Instead, one should
call uri.getRawSchemeSpecificPart(), which is exactly what the patch does.

(A little bit Off-topic): The general point here is that I am calling a form that is handled
in the super block. Since you cannot pass on request parameters from a POST call (that comes
from the browser) to the other (super) block called via the blocks-protocol (because the only
interface you have is the Source, where you can only pass information via the URI), you have
to put all parameters in the uri. I have written a simple input module that creates a "param1=alpha&param2=beta"
string from another input module (preferrably request-param) so that you simply call: "block:super:/dosomething?{params-to-uri:request-param}".
This might be integrated into Cocoon as a standard InputModule.
