[OpenMap Users] OpenMap Bug

From: Monte Philip V NPRI <MontePV_at_Npt.NUWC.Navy.Mil>

One of our developers found this:
OMGraphicList.findAll(int x, int y, float limit) throws null pointer exception.
This is because it uses OMGraphicList.findAllTest(int x, int y, float limit, boolean resetSelect, OMGraphicList addTo,OMGeometry omg, OMDist omd)
which calls OMGraphicList.findClosestTest(OMDist current, int index,OMGeometry graphic, int x, int y, float limit, boolean resetSelect) which returns null when graphic is not visible. This normal operation null return value is not properly tested for in findAllTest leading to the exception.
Solution: change line 1223 of OMGraphicList.java (openmap 4.6.3) from
            if (omd.omg == null) {
            if ((omd==null)||(omd.omg == null)) {
