"currently WARenderPhaseContinuation>>processRendering: sets contentType for a

"and that is sent before getting the document instantiated (which follows
immediately.)
Of course that is no issue if all you ever return are web documents using that application
'preference' e.g. iso-8859-1 and text/html. But my application is running in a
browser where a 404 page is just a 404 (i.e, an html page) but one content page may be
Content-Type h-markup and another may be Content-Type c-markup and this in English but
that in Telegu."
The system configuration option for a render loop subclass looks even worse from where I
sit - and quite unnecessary even if it is a design feature.
Not that other web frameworks are not stickier. One that almost gets this web content
type issue right is Apache Wicket. Some other frameworks do truly descend into properties
file/configuration Hades and some, like Lift, code themselves into an HTML-only
strait-jacket where text documents are concerned (bizarre for a language like Scala.) Yet
for bare-bones CGI, JSP and PHP, Content-Type is an utterly trivial matter. Only when a
framework is built do things start to go wrong on this one simple issue.
Doing something simple should be simple; doing something complex should be possible.

Hi Robert,
This would all be more appropriate on the Seaside list...
(I'm posting
there and CC'ing to Pier's list... could you follow up on
the Seaside
list if needed? thanks)
And we've been through this previously, if I recall. The
code you
mention below could probably be reduced to just "self
handler
documentClass on: self response stream codec: self codec".
handler
really never should be nil so what the default is is
pretty
irrelevant. If you are using a different class of Document,
you need
to configure that document class for your handler. If you
don't want
to use the web config UI, it's as simple as:
myApplication preferenceAt: #documentClass put:
MyDocumentSubclass
As for the other suggestions, I'm still not convinced. As I
said
before, I support your goal of outputting something other
than HTML,
but Seaside's RenderLoop is designed to render HTML and
WARenderPhaseContinuation makes several assumptions about
doing Html.
Its #updateRoot: calls several HtmlRoot-specific methods
and passes
the root to the Libraries, which also all expect an
HtmlRoot. If you
want to use something else with the RenderLoop, that's
fine, but I
think you'll need to subclass the Continuations to do it,
thus you can
override #processRendering: to do whatever you like. The
Continuations
were designed to be subclasses; that's why there's a
configuration for
them:
myApplication preferenceAt: #renderPhaseContinuationClass
put:
MyContinuationSubclass
myApplication preferenceAt: #actionPhaseContinuationClass
put:
MyContinuationSubclass

to even get my Curl app off the ground.
There are a few other places where I am hitting this
(most anywhere up in the
high level of the framework where
we drop in an HTML default rather than asking for the
default - even immediately after having asked for the app
contentType in this case ... which in my case is not
WAMimeType>>textHtml )
