I've got SWFUpload version 2.5 beta 3 attached to my Rails 2.3.2 application and it works great 75% of the time. The other 25%, I get types of failure.

The first failure is a failure to upload. The activity starts, but never actually sends the file to the servers. In my JS, when setting breakpoints, it stops between setting the post params and starting the upload (last two lines below):

var params = {
    "authenticity_token": authToken,        
    "photo[name]": $("#photo_name").val(),
    "photo[description]": $("#photo_description").val(),
    "photo[post_id]": $("#post_id").val()
};

params[keyName] = key;

swfu.setPostParams(params);
swfu.startUpload();

It just occurred to me that the file might not being queued, but I've got a handler attached to show the file name in a text box and that works consistently.

The second issue is this: Sometimes the response string is truncated. I'm rendering a partial in Rails without a layout to show the uploaded file data in my layout. Most of the time this partial comes through fine, but sometimes it comes through as only the first line, or only parts of the first several lines. The variables seem to be coming through into the view just fine. Any ideas?

Thanks!
