[OpenLayers-Dev] The dot in the ID name difficults jQuery

Here's the pull request for removing dots from identifiers:
I think I've got a clear picture of what you're trying to do. I totally
agree on the needless complexity of popups - they're the next thing to go
in my opinion. Regarding your efforts to try to use a qtip on the map, you
still shouldn't have to access the DOM elements used to render geometries.
The OL API provides you with methods to get the appropriate pixel location.
Anyway, I feel your pain. And I think we should work toward simple
tutorials demonstrating what you're trying to accomplish (use an arbitrary
widget lib to provide things like popups/tips).
