I have an application that is using a popup to display identify results. In Internet Explorer, if I click on a water valve, it will return results for the water valve and any other identified items in the tolerance area. On an iPad, however, I can tap directly on top of the same water valve and it will not return results. I do get other identify results from the same map service (ie. Water Mains) and it will return results for things like buildings that are fairly distant from where I tapped. Increasing the tolerance makes no difference.
This is an internal application behind a firewall and will be used on iPads, so I haven't tested it on other mobile devices and don't have a need to, so not sure what would happen on an android.
With firebug lite, I can see that the layer is queried and it returns a 200 OK result, but I'm unable to see the JSON response, so I don't know what was returned.
Any suggestions on how I can troubleshoot this?
