Hey Jeff,<br><br>I&#39;m not sure right off why this is happening so I&#39;m going to forward it on to the Ushahidi dev list (CC&#39;d). The OpenLayers list may also be a good a place to look.<br><br>Anyone out there have experience with this?<br>

hey brian - how&#39;s it going? We should figure out a way to get some drinks again soon; hangin&#39; out in Amman was a ton of fun.<div><br></div><div>Quick tech question: I&#39;ve been chillin&#39; with the Louisiana Bucket Brigade folks and we were trying to get our balloon map layers to show up in the Ushahidi map. I managed to get a TMS to appear in the OpenLayers sidebar as an overlay but i&#39;m not seeing the actual tiles.</div>

<div><br></div><div>Shannon from LABB said you and perhaps someone else had helped them with a layer issue before; am I missing something? i was just using:</div><div><br></div><div><br></div><div><div><div><font face="&#39;courier new&#39;, monospace">function overlay_getTileURL(bounds) {</font></div>

<div><br></div></div><div>in the Safari JS console. I tried it from a local TMS too to be sure it wasn&#39;t JS security stopping it. What&#39;s weird is that it&#39;s not actually even making requests for tiles; the issue occurs between when it accepts the new layer and makes tile requests.</div>

<div><br></div><div>Any ideas? Any help is appreciated. I could also bump this to the OpenLayers list or the Ushahidi list?</div><div>Jeff </div></div>
