Re: Advanced RequestTransport implementations. Any available to use?

Was my post asking if there was away to avoid doing our own version of batching.

Hi Thomas,

Unless I'm misunderstanding you I don't think what you suggest will work for what we are doing. We want to send the contents of the form to the server multiple times and call methods in our middle tier. 

The only way we could find to re-send the request attached to a form was to fail validation, which would mean that service methods would not be called.

That make any sense?

Regards

Sam

Thanks Thomas,

Lots to look at there. 

So I can send multiple RF requests over a single HTTP request (to send the contents of an Editor/RF tree multiple times, for validation) I have a nasty Transport.startBatch(String name) method. I have been wondering about marking the request somehow so I don't have to be so careful about using try/finally to clear any nasty state after an error. Still feels wrong assuming single threaded ;)

Batching comes for free with RequestFactory (call several methods on your RequestContext before you fire(), and combine several RequestContext in the same "batch" using RequestContext#append()); see also RequestBatcher to automatically fire() using a scheduleFinally (that's about moving the responsibility of calling fire())
