Would like some way to know when the file is finished saving. This is especially useful when saveAs uses a proxyURL and a user is waiting for the file to come back from the server. Currently, there is no way to inform user of this progress or when it completes.
Any response from Progress would be welkom. We definitly need a callback here for handling server responses (like exception handling).
Needed to schedule further script execution after success or failure of proxy request.
The server-side handler is doing more than passing back download stream, we are using server-side to submit into Documentum, we need the callback to check server if any error occur on server.
Yes this would be very helpful.
