File Upload with IFrame callback handling

[msimun]

Hi, we use smartgwt 2.5

Im doing file uload using UploadItem. The form action is redirected to IFrame created like this:

		HTMLPane pane = new HTMLPane();
		pane.setOverflow(Overflow.HIDDEN);
		pane.setID("fileUploadFrame");
		pane.setContents("<IFRAME NAME=\"fileUploadFrame\" style=\"width:0;height:0;border:0\"></IFRAME>");

I couldnt get the HTML pane to draw IFame, but that is not the issue.

Then i redirect the form to use the iFrame for submit:

		form.setTarget("fileUploadFrame");

And then on click of a button i want to submit the import form:

		if (!frame.validate()) return;
		frame.submitForm();
		dialogBox.hide();

The problem is that i want to handle the response from server which is in IFrame. I tried to submit it with callback etc. but nothing worked. How should this be done?

You need to write out an HTML response from the server that contains a JavaScript call out to the main frame. Here's a more detailed response on the same thing.
