[JAVA3D] Rendering problem with J3D V1_2.

[Malcolm Binstead]

I've been rendering a number of  stacked, partially transparent squares. I use an "OrderedGroup" node to avoid the normal transparency problems. This method works well with java3d1_1_3-win-opengl-sdk but the same application fails with java3d1_2-win-opengl_sdk below is the exception message raised by J3D's core s/w. java.lang.IndexOutOfBoundsException: Index: -1, Size: 10   at java.util.ArrayList.RangeCheck(ArrayList.java:490)   at java.util.ArrayList.get(ArrayList.java:304)   at java.media.j3d.RenderBin.findOrderedCollection(RenderBin.java:3076)   at java.media.j3d.RenderBin.findEnvironmentSet(RenderBin.java:3464)   at java.media.j3d.RenderBin.insertRenderAtom(RenderBin.java:2884)   at java.media.j3d.RenderBin.processGeometryAtoms(RenderBin.java:2415)   at java.media.j3d.RenderBin.processMessages(RenderBin.java:985)   at java.media.j3d.StructureUpdateThread.doWork(StructureUpdateThread.java:83)   at java.media.j3d.J3dThread.run(J3dThread.java:256) Any ideas what is causing this ? or of a known work around.   Malc
