Ajaxupload edit - Queue problem

I use a Formit call with some snippets (hooks and prehooks), to give users the ability to upload and edit resources.

Everything working properly except the files upload part. There I use AjaxUpload. The problem is that Ajaxupload when the user logs out, flashes the queue. So, when the user logout and login and try to edit resource, can't see the thumbnails. Data in the field is there but queue is blank.
