Echo Web Framework

Hi,

I use Echopoint.tucana(.FileUploadSelector) and Callback to upload file on server
and after upload I process file in method uploadSucceeded.

It works excellent in FF and Safari, but not in IE!

class Callback
//-----------------------------------------------------------------------------//
	@Override
	public void uploadSucceeded(UploadFinishEvent event) {
		// process
                Process(event.getFileName());
	}

After upload file on server in IE it doesnt call method uploadSucceeded, but file is all ok on server.
When I refresh IE (e.g. F5), then method uploadSucceeded is calling...
Can you try help me, what's wrong?

Thanks
Radek
