| """Script to remove Documents inside a Folder. | |||
| The new UI does not make any exceptions and treat this script as a generic Dialog Form Method. | |||
| Thus it receives form_id of previous form, dialog_id of current dialog and uids of objects from | |||
| previous Listbox. | |||
| The distinction between XHTML resp. RSJS interface is that in the later, this script receives | |||
| `uids` directly whether in XHTML it is given `selection_name` and must extract the uids from | |||
| the selection. | |||
| :param form_id: {str} Form ID of the previous View's FormBox | |||
| :param dialog_id: {str} current dialog's Form ID | |||
| :param uids: {list[int]} list of "selected" uids from the previous View (only in JS UI) | |||
| :param selection_name: {str} if present then user is using XHTML UI | |||
