undefined folder created even when sub-folder field is left blank while image upload
I had assets_allow_subfolder_creation set to TRUE intially which gave the option to create a sub-directory during upload. But even if I remove the default undefined sub-folder value and set it to blank(via the visible input field).
Then too the image is uploaded with undefined/image_name, on checking further the value field of the sub_folder field is not getting cleared.
