Form - asyn submission with file upload
After trying to async submit a form with a file upload field for a few hours I trolled around the message board and JIRA and ran across this:
http://issues.apache.org/jira/browse/TAPESTRY-1348
Is trying to async submit a form with a file upload field a DEAD END?
We tried to add the IFrame transport mechanism . . . however this did not trigger the request. Looking at the code it appears that the IFrame transport mechanism does not support async submissions etc. The tacos bug system has a related bug that mentions other changes that may be necessary to fix this:

Has anyone been able to successfully async submit a form with a file upload field?

Just ran into the same use case myself; I would like to use an asynch form
with a file upload in T4.1.5 app. I wonder if anybody has solved this
already. Carlos, how did you go about doing it?

Andreas,
thanks for the reply!
--> how did you enable the IFrame transport?
i added "dojo.require("dojo.io.IframeIO");" to a script file. However, this was insufficient. IframeTransport.canHandle() fails for two reasons:
- the response type that tapestry was requesting was "text/xml" - and as the bug you emailed me notes, that is not a supported format for the IframeIO
- it also appears that the IframeIO also requires the call to be synchronous. tapestry passes the request as async.
This might be a little naive, but can I avoid the problems the IFrame has with "text/xml" by specify that the response should come as JSON?

What this basically means for Tapestry is that async submit of forms
having files
cannot return the expected xml responses... however, i believe that the requests
do actually take place - how did you enable the IFrame transport?
Another idea (i think someone had mentioned doing this in this ML) is to have
a separate form just for the uploads or (even better) investigate how
to integrate
one of those flash uploaders...

See http://trac.dojotoolkit.org/ticket/524
Unfortunately, dojo decided to skip support for XML return types for IframeIO
(which is needed for file uploads) due to problems with making it cross-browser.
What this basically means for Tapestry is that async submit of forms
having files
cannot return the expected xml responses... however, i believe that the requests
do actually take place - how did you enable the IFrame transport?
Another idea (i think someone had mentioned doing this in this ML) is to have
a separate form just for the uploads or (even better) investigate how
to integrate
one of those flash uploaders...
