Re: [udig-devel] Change the style

[Jody Garnett <jody.garnett@xxxxxxxxx>]

That is interesting; there are a couple of places where styles are  
cached during the rendering process; but I thought they only ever  
where chased for the length of drawing a single image. Can you create  
a bug report with screen snaps showing the problem; and steps used  
etc...

If you want to look at the code the BasicFeatureRenderer  
implementation is what holds on to a geotools renderer when rendering  
features...

Also indicate it you are getting this problem with shapefiles,  
databases, or wfs data sources?
