Hi Mike,<br>
<br>
Thanks for the explanation, so far I think I understand.<br>
What I meant was the following:<br>
<br>
I can't figure out where I can get the layer variable from (containing the layer or layername that was right-clicked). You're passing the layer variable, but how do you get it to contain the right layer. Thats the main issue here. To simplify my problem:<br>
<br>
I have a context menu for the legend, containing an item: 'alert layer name', which functionality would be to do just that. I'd add these to lines to the Legend.Legendrenderer.<br>
<br>
this.alertLayernameAction= new Jx.Action(OpenLayers.Function.bind(alert( lyrName),null)); // (or something like that?)<br>
this.alertLayer= new Jx.MenuItem(this.executeRasterQueryAction, {label:OpenLayers.i18n('alert layer name')});<br>
<br>
My issue her is where do I get lyrname from? Is the name of the node that was right-clicked available somewhere?<br>
<br>
Hope this is clearer, thanks so much!<br>
<br>
Tom<br>

<br>
Then your getRasterQuery method would look like:<br>
<br>
function getRasterQuery(layer) {<br>
var temp = layer.name;<br>
...<br>
}<br>
<br>
For the OpenLayers.Function.bind method, the first arg is the method to <br>
be bound, the second arg is the object to bind to (object will be 'this' <br>
inside the method), and then the rest of the arguments will be passed to <br>
the bound method as arguments.<br>
