EXTJS Fileupload - Problem with IE8 security bar

Question

I\'m trying to make an EXTJS application to send email with an attachment. So I have a very basic form that include textfield for the subject, another textfield with inputT

Answer 1

On the server side, you MUST do the following, even though it looks a bit odd:

• set the response type to "text/html"
• send {"success": true} as JSON object

the response type makes the browser render the response in the iframe ExtJS uses ExtJS reads that from the DOM, and interprets it as JSON, looking for the success field.
