Images tab state after validation fail

[sintro]

Currently all the images, selected as attached in Images tab (for any model in admin panel) resets to their persisted in database state, if the record was not saved due to validation fail. I mean, there are no "image field" memorization.

[bricesanchez]

Could you provide us a step by step to reproduce the error and a copy of your Gemfile.lock file ?

[sintro]

Sure, this is my current Gemfile.lock

BUNDLED WITH
   1.11.2

This is how to reproduce this situation (don't think that it is correct to call this "error" or bug, this is just the lack of UX):

1. Go to any page editor or new page creating window. Of course, refinerycms-page-images should be enabled.
2. You can fill all the fields: body, pretty url, slugs. Select some images to attach in Images tab.
3. Leave page Title empty - this way the record will fail the validation checks.
4. Press Save
5. Now you see the validation error (Empty title), and all filled fields untouched (rendered with unsaved @page object). But if you will go to Images tab, it will be in the same state, as it was when you began to edit/create page (it will have previously attached images only or it will be clear).

This is not error or bug for my opinion, and to fix this it is just necessary to write some more code for controllers to keep the images between different actions and then present them in view with validation errors.
