I have the following problem with ext-4 application, I upload multiple images to the server, to create a function that pressing a button that creates a new named FileField photo  to take them to the server as an array of images . The problem is that when sending data to the server only sends FileField last image that was added to the zero position of the array. It's like missing a setting that would allow me to upload multiple files to the server, or that the last element is inserted FileField which recognizes the form.
if anyone could help me I would appreciate, I'm engaged for more than three days. Sorry de translation.
