If you are using SharePoint you should look into the product "QlikView Web Parts" - http://www.qlik.com/us/~/media/Files/resource-library/global-us/direct/datasheets/DS-QlikView-Web-Parts-for-Microsoft-Sh… . It should be able to help you with what you want to do.
Thank you Erik!
I've been looking at this blog post: QlikView Mashup Examples & Documentation (QlikTip #48)
and in particular this section of it: QlikView Mashups - Simple Document Integration
It seems to suggest that first of all, Workbench is required, and secondly, that if someone wants to display an entire QVW application that the opendoc.htm method is required (I don't think Qlikview webparts allow one to display an entire Qlikview app, only a Qlikview object - Sharepoint web parts allow you to display an entire app I believe). From what this blog post says I think we're using the correct filtering method, it just may be that the folks wanting to implement this don't have Workbench (they're using Sharepoint 2010 and IE8-10).
Does anyone have any opinion or insight or additional info on the above?
