What is happening is the this.map.getLayerPxFromLonLat(someLoc) call is returning null, however you are trying to access the x member as if something valid were returned. You need to check the return values of the functions before trying to use them. I'm not sure why the ext-base.js addition has any effect though.</div><div><br></div><div>Dan</div><div><br></div><span id="OLK_SRC_BODY_SECTION"><div style="font-family:Calibri; font-size:11pt; text-align:left; color:black; BORDER-BOTTOM: medium none; BORDER-LEFT: medium none; PADDING-BOTTOM: 0in; PADDING-LEFT: 0in; PADDING-RIGHT: 0in; BORDER-TOP: #b5c4df 1pt solid; BORDER-RIGHT: medium none; PADDING-TOP: 3pt"><span style="font-weight:bold">From: </span> julia paredes <<a href="mailto:japr94@hotmail.com">japr94@hotmail.com</a>><br><span style="font-weight:bold">Date: </span> Wed, 20 Jun 2012 00:23:22 +0000<br><span style="font-weight:bold">To: </span> Dan Ramage <<a href="mailto:dan@inlet.geol.sc.edu">dan@inlet.geol.sc.edu</a>><br><span style="font-weight:bold">Cc: </span> geoext <<a href="mailto:users@geoext.org">users@geoext.org</a>><br><span style="font-weight:bold">Subject: </span> RE: {SpamScore: ssss} [Users] GeoExt breaks OpenLayers Heatmap<br></div><div><br></div><div><style><!--
