I've investigated this issue and realized that the problem isn't
receiving the unfiltered character, but writing it to the client. Here's
the situation: my component receives a string parameter that is simply
passed to a javascript object. This parameter is a css selector rule as
supported by the prototype library:
http://www.prototypejs.org/api/element/getelementsbyselector
http://www.prototypejs.org/api/utility/dollar-dollar
The javascript object uses this rule to locate the set of elements upon
which it should operate, allowing greater control of how a user
structures their template markup. So in my case I want to select all of
the immediate child divs, I can use the rule '> div'. The problem is
that when the final markup sent to the browser, this string is filtered
as '>' - this breaks my rule. After some digging and *some real time
discussion with other developers (fanf) in the IRC channel (#tapestry
irc.freenode.net)*, I realized the problem is a bit deep.
To add my scripts my component employs the PageRenderSupport
environmental. Longer explanation made short, this ends up in my script
code (added by addScript()) being added to the document using
Element#text. This method does the filtering, and there's nothing I can
do about it.
The only option I think I have is to contribute by own implementation of
PageRenderSupport. However since I can't just extend
PageRenderSupportImpl and delegate to it (its an internal service), this
seems to leave me stranded with the task of reimplementing it from scratch.
Obviously I don't want to do that, so I'm asking for some input from
those with a deeper knowledge. How can this be done better? Does it
makes sense to use Element#text instead of Element#raw in
DocumentHeadBuilderImpl#updateDocument, since where writing script code
and not markup?
sincerely,
chris

My component takes a parameter with a default binding prefix of
'literal'. This parameter needs to be able to receive strings with
characters like '>', but apparently the literal prefix causes them to
be converted to entities. How can I pass unfiltered characters to my
component as a parameter?
Thanks,
