[Geoserver-users] GS 2.0-beta1 Label Priority problem

Hi,

I’m new to Geoserver, but it looks like I’ve jumped straight into the deep end. I’m having an issue with the option.

I have set up rules to render “street” and “minor road” road segments. In the dataset we have some streets and minor roads with the same name. However if I enable VendorOption “group” on both rules GS prefers to label the street rather than the minor road. Where as it should be the other way around. I tried adding an attribute to the dataset called “label_priority” and specified a element. But it doesn’t work as expected.

The only way I can get it to use their respective Labelling styles is if I set group=false on the street. But that is not desirable as I do want to group labels.

Dataset extract:

road_name road_category label_priority

“Saint Vincents Rd” 5 1

“Saint Vincents Rd” 4 2

STREET_1

Priorities and groups together... I think I never tried to use them
in practice. Can you open a bug report at jira.codehaus.org, attaching
the SLD and enough sample data to reproduce the problem?
