Hi Robert,
We tried to use your latest Identify Widget 2.5.7 to identify the parcel boundary layer. It seems to us that it did not work on the layer in cached map service. Could you please give us some suggestions on what could be wrong? We appreciate your help very much.
Update:
I just used Firefox with Firebug to view our Flex Viewer application. It was found the parcel boundary was identified by your widget. However, the InfoWindow was not popped up. I can use your widget to identify the other layers which are not in cached map services. I revert your widget back to 2.5.5. The widget worked for the parcel boundary layer in the cached map service. Any ideas?
