[OpenLayers-Users] Is there a way to assign a dynamic label on vector layer?

[Andreas Hocevar]

Hi,

the OpenLayers configuration looks correct. But by default, you cannot use "name" as feature attribute in WFS. If your WFS is GeoServer, you can override this in the Services - WFS settings by checking the "Override GML Attributes" checkbox.

My layer is currently defined as follows (note that I have used the substitution "${name}" in the label parameter).  Currently this renders the vectors with the label as "undefined".  I'd like to use the name field from the data source as the label for the vectors.  Please let me know if I can provide more detail.
