I&#39;ve tried the fix, but with the last SVN, doesn&#39;t works (03/31/2010). This<br>
is the code in the line 110:<br>
<br>
110 var options = {<br>
111          div: this.domObj,<br>
112          size: this.oSize,<br>
113          minRatio: this.nMinRatio,<br>
114          maxRatio: this.nMaxRatio,<br>
115          mapOptions: this.oMapOptions,<br>
116          layers: [layer]<br>
117        };<br>
