Hi, I think I was having the same issue: http://osgeo-org.1560.x6.nabble.com/SLD-Stroke-Dasharray-Property-td5083512.html
Basically the dash array property only supports literal expressions (I am in doubt if PropertyName is or not supported ...) I solve the problem prepared the patch and so on, but I still waiting that some in an higher position than me sign the contribution agreement ...
