[OpenLayers-Users] StyleMap and ModifyFeatures aren't compatible ?

[Alexandre Dube]

Sure I'll try, but anybody correct me if I am wrong with the explanation 
please.

The vertices are vector features too that try to be drawn on the same 
layer.  If a uniqueValueRules is set, then the a drawn feature must 
respect it.  Since the vertices don't ( they don't have the related 
attribute value, therefore don't respect the rule ) they are now drawn.

Well, in fact they are created, but not shown.  The elseFilter:true 
means : if the feature doesn't respect the uniqueValueRules, use "this" 
following rule instead.

Am I right ?
