[udig-devel] Shapefiles and sld:ExternalGraphic

Title: Shapefiles and sld:ExternalGraphic

Hi,

I'm using uDIG 1.1 RC4 and in my program I create a shapefile of type MultiPoint (shape type 8). Using this shapefile with uDIG works fine as long as I use a sld file with sld:Mark: All of my about 50 points are shown.

But when I try to use a sld file with sld:ExternalGraphic only 1 of those is shown although more than 1 are in the range of the viewport. When that one currently shown is not in the viewport anymore (because of panning or zooming in) another one is shown. But as I said always only 1 at a time is displayed.

Here are the diffs of the two sld files:

Any hints where I do something wrong?
