Troubleshooting SDK

Hi,

I just tried making a cursor system and whenever i try loading a cur ico or ani file using
(JmeCursor) assetManager.loadAsset(“Textures/Cursors/cursor.cur”);

[java]Sep 26, 2013 11:06:03 PM com.jme3.app.Application handleError
SEVERE: Uncaught exception thrown in Thread[LWJGL Renderer Thread,5,main]

I also get this error when running the sample cursor project

Is this currently broken?

Thanks

I think this is due to a image format problem I was trying to load cursors and ani files directly downloaded from http://www.rw-designer.com

The code seems to have issues with this

I edited the cursors in RealWorld Cursor Editor for cur files and AniTuner for ani files and it seems happy to load them after they have been recreated using those tools

I think this exception could probably be caught at

java.lang.ClassCastException: com.jme3.asset.AssetKey cannot be cast to com.jme3.asset.TextureKey at com.jme3.texture.plugins.AWTLoader.load(AWTLoader.java:196)

and echo that the image is probably an incorrect format

Class cast exception doesn’t seem to = dodgy image, not very user friendly
