Hello all,<br clear="all"><div><br></div><div>I'm facing a small but annoying problem with vector legends. I'm using JSTS (which i think it is an awesome contribution for geoprocessing operations on the client side) to compute buffers. So the user defines the parameters to compute a buffer and a new vector layer is added with the result. Untill now everything is fine, and GeoExt.LegendPanel shows the legend for this layer. In the app, the user has also the possibility to select several layers and completely remove them from the map. It is exactly here that the problem arises. After removing a vector layer from the map i start to get an error related with vectorlegend.js. From that point onwards, everytime i make a zoom in the map i get the following error:</div>
<div><br></div><div><span class="sourceRowText">this.layer is null (on line 256 of vectorlegend.js: this.layer.map.getScale())</span></div><div><span class="sourceRowText"><br></span></div><div><span class="sourceRowText">This only happens after removing vector layers from the map. So i thought i had to manually remove the layer from the legendpanel but, as expected, the layerstore of the legendpanel is synchronized with the mapPanel layerstore and, therefore, the layer is no longer present at both stores.</span></div>
<div><span class="sourceRowText"><br></span></div><div><span class="sourceRowText">So, what might be the issue happening here?</span></div><div><span class="sourceRowText"><br></span></div><div>Regards,</div><div>Hugo</div>
