In trying to use the HTML 5 Web Form Viewer from the 2015 Q2 release I have ran into one issue. What I am trying to do is use viewer as a generic viewer for one of several reports that will will be loaded later. Each report is different with different parameters, etc.
I am not looking to set a report source at page load or beforehand. But everytime I do not set the report source it receive and Object reference not set....
Is it possible to use html 5 web report viewer server control without setting the reportsource before runtime?
