Hi,
I am trying to add hover over tooltip to my application, but once I add code for tooltip, the dialog is not showing up and now even the circle that is used to draw a buffer and select features disappears, here is what I have so far, if anyone take a look and point out what is missing or needs to be corrected, that will be great, thanks!
