I am embedding Qlik objects in SalesForce using VisualForce page. I am passing the customer number from SalesForce to filter the Qlik object for the specific customer number. It all works fine, except that Qlik will return all record if it can not find the passed customer number, how do I force it to keep the filter and just display an empty page?
<apex:page standardController="Account" tabStyle="Account">
<apex:pageblock >
<div style = "display: inline;">
<apex:iframe src="https://server.net/single/?appid=123432-1223-2121-1212&obj=pSjvJu&opt=currsel%2Cctxmenu&select=clear...}" frameborder="0" width="100%" height="900" />
</div>
