color:#1F497D'>Currently, I've created my own control that adds an attribute to
the feature, based on an option passed when the control was created, and this
is working. But it seems a bit kludgy, and is likely to break if a future
version of OpenLayers makes changes to how DrawFeature.drawFeature() works. So
I was wondering if there was a better way to do it.<o:p></o:p></span></p>

<p class=MsoNormal style='mso-margin-top-alt:0in;margin-right:0in;margin-bottom:
12.0pt;margin-left:.5in'>You can add a listener on the "featureadded"
event of your vector layer. In this listener callback function, you should be
able, for example, to set a specific value for an attribute of the added
feature. Then using a StyleMap on your layer you should be able to draw the
given feature with a specific color depending on the attribute value.<br>
<br>
I hope this helps.<br>
