[OpenLayers-Dev] SelectFeature outFeature method

[Slawomir Messner]

Hi,
I think, this is because if the "string" is executed there is a second 
control(like maybe in your case) which has highlighted the feature 
before so it is the previous highlighter and it highlights the feature. 
It is not unhighlighted because it's highlighted by the previous 
highlighter. Because it is not highlighted the event is not triggered. I 
think this behaviour is unexpected if you see it first because you 
always get an highlighted event but in this case not the symmetric 
event. So you cannot know when your mouse is out except you change the 
SelectFeature-class. I hope it clears a little what's happening.
It think too this behaviour could be changed, because you should always 
be aware for a second select control (and listen to it if you want) if 
you want to monitor all highlighted features. In the most cases you want 
to know if a special SelectFeature unhighlighted a feature. The thing is 
that you have to check the style to know if a feature is highlighted, 
selected features are in the selectedFeatures array, highlighted 
not(like you can read it in the new documentation;)).

Slawomir
