Description
Look at the attached screendumps.
Black arrow points at the polygon being queried.
identify_bad.png shows how it is now. This is wrong - although the smaller polygon inside is not being queried, it looks like if it was too.
identify_ok.png shows how it should look like - it is clear which polygon is queried actually.

I had a detailed look at this. The issue lies inside QgsRubberBand. The polygon drawing routine in that class iterates over multipolygons, but not rings. It will be possible to add this functionality (and I agree we should) but I dont think its a good idea to make the invasive changes required right at the end of code freeze / on the point of release. I'm moving this issue over to milestone 1.0.0 and I'll attend to it in the next release cycle.

Hi,
I gave a try to this on qgis 1.2 (rev. 10988).
If the select tool is used on the outer polygon it selects just it, using the tool on the inner one, it selects both.
This means that this bug has already been fixed?

I noticed that by selecting the proper row (the one of the inner polygon) in the attribute table, it possible to select just the inner or the outer polygon. The select tools does not behave the same, so I guess this is still to fix. Nevertheless should be easy. Pushing the milestone to 1.2.

Well,
if Qgis is doing it wrong it is not alone. I just tested gvSIG 1.2 and it behaves exactly the same way (see may last two comments).
So, please leave feedback, if this is the right behaviour we can close the ticket.

I believe that this can be closed now. See attached screenshots to see how it worls the identify tool now.
Clicking on the outer polygon it kind of highlight also the inner one, but the result window do not show it. Moreover if you click again on the inner polygon it will get a more dense color and the result appear in the result windows.
Then if you click on the proper result in the result window you'll get highlighted just the inner one.

I am reopening this ticket, because of the behavior of 'identify tool' in current trunk which is the same as in 'identify_bad.png' picture.
Ticket #2190 is duplicate to this issue.
There was also thread in mailinglist r1.
