My wild guess is that the ASP.NET page does not accept the ajax client to be loading the QVW, and instead the IE plugin is loading the QVW. Qlikview Extensions only work with the Ajax client.
If this is not the case - if you are sure that the QVW is loedad in the Ajax client - I have two extensions that I use for testing functionality. See if any of theese work in your environment:
Extension 1: Simple Clickable Example: A simple Example of some clickable boxes. Testing that the Raphael Engine works.
Extension 2: Simple Test: A simple test that extension functionalty works. (No vector integration, only a simple HTML page)
Good luck testing!
It looks like we're in a tangled web of Authentication torment! (QV & IIS).
Thanks very much for your examples, it helped us get closer... Right now:
SimpleClickableExample loads and displays fine, provided website is hosted within IIS on the same physical machine as QVS.
When I run the same website hosted on my local dev machine IIS, SimpleClickableExample loads, but the count(F2) box is completely blank.
Have you any other wild guesses??
Thanks again, very much appreciate your time.
