[Users] legend

[pedrocostaarma at sapo.pt]

Hi guys,

I am using geoext 1.1 with openlayers 2.11.
I have a few point layers (WFS) with associated styles where I pass an
image adress  to 'externalGraphic' parameter like
this 'http://test.pt/images/point.png'. Works well. My problem is, when I
make this parameter dynamic to use features attribute value 
like that  "http://test.pt/images/" + '${cod}" + ".png" the layers symbols
display the graphic cool but we cannot see them on legend.
You can see an example on attached image. Somenone knows hot to fix that?

thanks in advance
