I have problem with Magento UI component form.
When I click on this form and save it database with this row will be updated. Second time when I entered on that same slider, the values are checked but problem is when I want to save that instance, then every data from form RELATED banners disappear.
In POST form I don't have any values from form "Related Banners" - very propably that it's caused by ui component. How can I pass data (for example Checked column (checked/unchecked)) to save Action after edit?
