<DIV>If I remove the FILTER on the layer, the whichshapes code works correctly and returns all the shapes within the extent.</DIV>
<DIV>Let me know what you think.</DIV>

an attribute based feature search." How and where is the attribute based search query included in this method? <BR>JJ<BR><BR><BR> <BR></DIV></DIV></div><br>
