[OpenLayers-Users] triggering a featureselected event?

[Chris Abraham]

Thanks.  What's the right way to use layer.events.triggerEvent?  I  
tried this:

layer.events.triggerEvent('featureunselected', layer.selectedFeatures 
[0])
and
layer.events.triggerEvent('featureunselected',  
{'feature':layer.selectedFeatures[0]})

but nothing happened.
