I'm having a problem with drag drop on a document library. The document library has a WebPart view filter to show only the document from a selected task WebPart. This works because the document library has a lookup column to the task title.
If one normally uploads a document by +Add document link all is ok. People get shown a form and fill in the lookup task column.
However when people drag a file onto the document library. The webpart link of the selected task is ignored. And documents are uploaded without a task assigned.
How to make it so that the info provided by the selected task from the webpart filter is used?.
