Hi Volker,
I took a look at the SRIDStyle code, but I'm just not familiar enough with
it to confirm or deny your conclusions. LayerListeners are confusing and I
avoid them whenever possible. SkyJUMP doesn't use SRIDStyle and I'm not
sure why it was implemented this way in OJ. Perhaps the author or someone
more familiar with it will respond.
regards,
Larry
