[OpenLayers-Dev] Vector layer - Hover and click at same time

[Eric Lemoine]

Hi. The select feature control's primary goal is select features, i.e.
change feature style to the select render intent. So if you use two
select feature controls on the same layer, one with hover and one
without, when moving over the feature the hover control will select it
and on click the click control wont do anything because it'll figure
it's already selected. What you probably want is create your own
feature handler-based control. That control's purpose would be to
execute a uses-defined func when a click or hover occurs on a feature.
I even think that such a control should go in OpenLayers and that the
select feature control should be based on it. Patches very welcome :)
