Hi Mason,
You pom.xml looks fine to me.
The reason that I asked you to check is that the NullPointerException
you and others were seeing was caused by a problem in the
MapViewport.getScreenToWorld() method.
The top bit of the error trace you posted was:
java.lang.NullPointerException
at java.awt.geom.AffineTransform.<init>(AffineTransform.java:471)
at org.geotools.map.MapViewport.getScreenToWorld(MapViewport.java:351)
The NPE was being thrown by the AffineTransform constructor when it
was passed a null value by this stupid code (which I'm afraid I
wrote)...
public AffineTransform getScreenToWorld() {
return new AffineTransform(screenToWorld);
}
But that method was changed yesterday to this...
public synchronized AffineTransform getScreenToWorld() {
return screenToWorld == null ? null : new
AffineTransform(screenToWorld);
}
So there doesn't seem to be any way you can get the same NPE.
To make sure that what you are seeing and what I am testing relates to
exactly the same code can you try the following please:
- delete the org/geotools folder from your local maven repo
- build your project again, forcing maven to download the jars
- post the error trace (if you get one) to the list
Thanks for your patience !
Michael
