[OpenLayers-Users] Highlighting Selected Tract

[Gery .]

Definitely Jerome, you should follow Phil's idea, I think your problem is that your features are not properly called/filtered, I think the best is to use a protocol and play with it (use it inside a function and use return), so at the end you can display one feature at the time, but having all the features already called, so you use a for loop to display them.

Nope. They should be part of the map div, under the selectlayer. First thing
though is step through code, make sure addFeatures is actually called. If
you use the lib version of OL, you can step into addFeatures as well.

The kind of thing you are doing, (point select, polyselect) I do with
DrawFeature controls. I have featureadded event handler attached which
creates a spatial filter. I read a WFS protocol with this filter and call
addFeatures (and all the other logic) on the return. The method gives me a
single point to process spatial returns and control over the fiter. There
are probably easier ways but as a application get a lot of function added to
it, control gets more important.
