Firstly, thanks for your plugin.
I have a multi-page form with 4 pages, with your plugin set on pages 2 and 3.
1) The plugin is not moving files from tmp dir at submit (form 4). And files are being deleted because they are on a TMP dir that is managed by the plugin. It works if all plugins are on the last page.
2) The plugin is showing the "Flash/Silverlight/HML5" error without explanation on page 3, although it's working. The page 2 is ok.
3) I need requiring the user to upload files, but your solution using gform_field_validation_x_y is always being called with an empty $value. If it had anything, even temporarily, it will do the trick. Any ideas?
Those problems are driving me nuts, and my website is currently online.
Please help! Thanks in advance.
