We are running SharePoint 2010 and Quick Apps 6.3.  We have a document library containing over 5000 rows, thus exceeding the list view threshold.

Documents are uploaded to the library using a linked field on a qListView that has a CAML filter on an indexed field.  Clicking on the linked field displays a qListForm/UploadDocument page.  (We use the linked field so that http parameters can be passed to populate metadata.)

When I upload a single document (by clicking the "Browse..." button on the upload page), the document uploads and gets checked in successfully.

When I attempt to upload multiple documents (by clicking on "Click here to upload multiple files..." on the upload page), the error "The attempted operation is prohibited because it exceeds the list view threshold enforced by the administrator." displays.  There is no opportunity to upload multiple documents.

This works as expected when the list view threshold as not been exceeded.

Is there a way around this?  Is there another field that needs to be indexed in order to make the multiple document upload work?

Thank you.
