<p class="MsoNormal">I've made a small change to the WmsLegend class and now it works perfectly.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">I've just added the following code inside the getLegendUrl method (at line 145):<o:p></o:p></p>

</div>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">Obviously this assumes that if legendURL is different than an empty strig, it will override the url returned by the styles definition.<o:p></o:p></p>

<p class="MsoNormal">Hi all,<o:p></o:p></p>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">I'm building a tree panel similar to the example LegendTree. So far so good, I'm able to use gx_wmslegend ctype to show the legend below each node in the tree.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">However there is a case where i need to override the legendURL and point it to a specific image instead of using the default GetLegendGraphic.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">I have sucessfully implemented this override in a GeoExt.panel.Legend by "manually" seting the layer record legendurl field [eg: layerRec.set("legendURL", rec.data.legURL);]<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">When trying the same approach on th gx_wmslegend it doesn't work. I was reading through the docs of this xtype and it states that <span style="font-size:10.0pt;font-family:"Helvetica","sans-serif";color:#484848">the image can be read from
the styles field of a layer record</span><o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">When looking at the layerModel i cannot see this field defined. So my question would be, where should i set this styles field? GeoExt layer record? Openlayers layer record? How would it look like?<o:p></o:p></p>
