[Seaside] Seaside text/plain output problems

Sat Jun 2 00:13:00 UTC 2007

Hi everybody!

I'm working on a project using Seaside for the first time, and for 
various reasons it needs to output Content-Type: "text/plain" 
documents.   So having no idea, how Seaside's internals work I started 
sticking in random 'self break' statements, until I found a place that 
the Content-Type was set.  What I did so far was:

WAHtmlRoot<<contentType
    ^ mimeType ifNil: ['text/html'] ifNotNil: [mimeType]

WAHtmlRoot<<mimeType
    ^ mimeType

WAHtmlRoot<<mimeType: aString
    ^ mimeType := aString

This at least allows me to change what was previously a hardcoded 
content type, but it wasn't enough to allow access from the viewer as I 
couldn't find an obvious way to access the response object through the 
html one so:

WAHtmlDocument<<response
    ^response

WAHtmlDocument<<response: aResponse
    ^response := aResponse

WARender<<buildResponse
    | response document |
    self updateUrl: url.
    context actionUrl: url.
    response := self newResponse.
    response headerAt: 'Cache-Control' put: 'No-cache'.
    document := self session outputDocumentClass root: self buildDocRoot.
    document stream: response stream.
*    document response: response.*
    context document: document.
    root decorationChainDo: [:ea | ea renderWithContext: context].       
    self writeOnLoadOn: document.
    document close.
    ^ response

At this point I could now alter the response within my View class:

TestView<<renderContentOn: html
    html context document response contentType: 'text/plain'.
    html text: 'Testing 1 2 3'

Generates a page of type 'text/plain' but the page is just the 
javascript load preamble:

title="Render Time">0</span>/<span title="Callback Time">0</span> 
ms</div><script type="text/javascript">/*<![CDATA[*/function 
onLoad(){}/*]]>*/</script></body></html>

So my question is how do I override this!

I noticed that I can override the response stream in my View object, but 
there's a continuation which gets called which will overwrite whatever I 
put in the stream.  Am I going about this totally the wrong way?
