Re: [udig-devel] filtering contents of rendered layers

[Vince Darley <vince.darley@xxxxxxxxxxxx>]

I'm trying this now:

At 20:38 29/10/2007, Jesse Eichar wrote:
>layer.getBlackboard().put ( 
ProjectBlackboardConstants#LAYER__DATA_QUERY, filter);

via code like this:

static void addFilterToLayer(ILayer layer, java.util.Map<String, 
Filter> layerFilters) {
  Filter f = layerFilters.get(layer.getName());
  if (f != null) {
    System.out.println("Filter for " + layer.getName() + " is " + f);
    layer.getBlackboard().put(ProjectBlackboardConstants.LAYER__DATA_QUERY, 
f);
  }
}

the output on the console is:

Filter for Schedule location details is [[ Driver ID = Refuse Team 3 
] AND [ Day = 1 ]]

Which looks ok to me (the filter has definitely parsed ok, since the 
above string is not exactly how I created it), but, this has no 
effect at all on rendering of the layer.  I still see all the 
geometries in the layer in my rendered report, even ones which don't 
have matching attributes for 'Driver ID' and 'Day'.

Anything obvious I'm doing wrong?  Any pointers to debugging this?

thanks,

Vince.
