Interesting. The leading slashes seem to be the problem.
Changing the upload_url and file_destination_path are not going to change anything because those are all set in the BulkUploader_Controller when the field is instantiated.
Go to that section of the BulkUploader_Controller code (line 130-ish)
$fields = new FieldSet(
'file_upload_limit' => '100', // how many files can be uploaded
'file_queue_limit' => '100', // how many files can be in the queue at once
'browse_button_text' => 'Choose files...',
'upload_url' => '/'.$this->RelativeLink('handleswfupload')
try removing the leading slash on upload_url
Almost there! Thanks so much for all your testing.
I have installed the latest svn files and did a dev/build.
In the Manage Files section on the right, I see the drop down menu "--Import from folder--" without any import button, but when I select a folder, nothing happens. What am I supposed to see? How is this supposed to work?
I can see it using your sandbox, so the issue is not browser related. I wonder if it's once again related to defining an absolute URL instead of a relative one. What is actually loading in that iframe and where can I change its url to define an absolute url?
By the way, when I select the Uploads folder (which has a lot of files), in Safari I do not get a vertical scrollbar (which I get in Firefox), Hence, the list is prematurely cropped and I cannot see the "import selected file(s)" button down the bottom. I have not tested this in IE. You may want to look at how you have defined the iframe. The overflow appears to be hidden.
Also, it might be worthwhile to properly indent the nested folders so that you can see the folder hierarchy. Just a though!
