View Full Version : Use FileUploadField with Async call

1 Feb 2010, 1:12 AM

I am using FileUploadField in one of the modules of my application to upload an excel file. As a common practice; FileUploadField is used along with a FormPanel where we need to submit the FormPanel. The action is submitted to a HTTPServlet where one can parse the excel file.

I would like to know if there is a way where we can use FileUploadField using RPC. The reason being; my module requires me to validate the uploaded file and return validation messages. Since with FormPanel I am submitting the request to a servlet, there is no callback object. If anyone has done such an implementation would request to assist me for the same.
