Custom WAErrorHandler

I'm playing with WAErrorHandler lately and wonder how can I generate a
clean response from it.

For example:

GTRootComponent>>renderContentOn: html
self renderLoginTabOn: html.
self renderSocialLinksOn: html.
self renderMainContentOn: html.
Dictionary new at: #blop.
self renderFooterOn: html.

My custom handler looks like this:

handleDefault: anException
| content answer |
self sendFailFor: anException.
anException isResumable
ifTrue: [ anException resume ].

content := WAHtmlCanvas builder
fullDocument: true;
rootBlock: [ :root | root title: 'Unable to proceed' ];
render: [ :html | html heading level: 1; with: 'Error !' ].
self requestContext respond: [ :response |
response
internalError;
nextPutAll: content ]

The handler handles the KeyNotFound fine but the response is already
filled with the rendering of renderLoginTabOn:, renderSocialLinksOn: and
renderMainContentOn:.

Is there a way to draw on a clean response ? I guess it's pretty
obvious, I've looked at the requestContext and responseGenerator but
cannot find how to do it :/

Cheers,

Francois

Are you using a streaming server (eg. WAListenerAdaptor)?

Hi Philippe, sorry for the late reply :/
I'm using ZnZincServerAdaptor

Uh oh, you found a bug [1]. You'll have to add a

response stream reset

and will probably have to add this method on GRCodecStream and
delegate to the stream instance variable.

Cheers ! I'll test that, should I commit something somewhere ?

No, we'll fix.
