IllegalStateException after creating another ViewPort

Troubleshooting General Help

Hello there,



I’m using SVN jme3 and after adding another ViewPort using createPostView on my SimpleApplication’s renderManager instance within the simpleInitApp method. I get the following error:


08.03.2011 17:35:23 com.jme3.app.Application handleError
SCHWERWIEGEND: Uncaught exception thrown in Thread[LWJGL Renderer Thread,5,main]
java.lang.IllegalStateException: Scene graph is not properly updated for rendering.
Make sure scene graph state was not changed after
rootNode.updateGeometricState() call.

I don't really do anything with the new ViewPort besides adding the simpleApp's rootNode to it. Also, the rootNode contains only one element which is a BitmapText with a BillboardControl added to it. Removing the code for creating the new ViewPort or, removing the code for adding a single BitmapText element or removing the code for adding a BillboardControl to the BitmapText instance solves the problem.
My guess is adding the BillboardControl within the initApp method is the problem - but where should I put it instead?

kind regards,

The scene in the post and pre views are not updated automatically, you have to call rootNode.updateLogical and -GeometricState() for those root nodes yourself each update.

3

Shouldn’t the rootNode’s update methods already be called from the main view? The post view has the same rootNode after all.

4

did you try it?

Yes and no. I created another node and added that to the new view. On the new node I now call updateLogicalState and updateGeometricState just as you said and that works.



Thanks a lot!
