Post-processing pipeline causes error when placing "SceneGrid" object into 3D scene

Question

Hi,
first want to thank you guys for the great work with proscenium and the awesome features.
I was going through the examples and found a bug. I tried a combination of the examples "TestLines" and "TestPPEncodeDecodeHDR".
The post processing pipeline somehow manipulates the render sates/vertex program in a way it crashes as soon as it should perform the drawTriangles call for a "SceneGrid" object.
It does not seem to be related to my particular post processing setup - I tried TestPPBloom and TestPPEncodeDecodeHDR from the examples. The post processing pipeline seems to work fine with a 3DS model (Teapot) .
  //add grid
  scene.addChild(new SceneGrid());
  //setup post-processing
  if(true) {
instance.createPostProcessingColorBuffer();
instance.colorBuffer.targetSettings.useHDRMapping = true;
instance.colorBuffer.targetSettings.kHDRMapping = 4;
var colorToPrimary:RenderGraphNode = new RenderGraphNodePPElement(instance.colorBuffer, null, RenderGraphNodePPElement.HDR_DECODE, "Decode HDR" );
colorToPrimary.addStaticPrerequisite(instance.colorBuffer.renderGraphNode);
instance.renderGraphRoot.clearAllPrerequisite( );
instance.renderGraphRoot.addStaticPrerequisite(colorToPrimary);
This gives me the following error:
Error: Error #3607: Stream 2 is set but not used by the current vertex program.

Hi John,
Pls check in SXI_CACHE to verify that the BPM(active in Integration Repository) has the latest version active on the ABAP stack.(I am saying this because you mentioned that a mapping step was missing..is it not..)
go to SXI_CACHE --> Integration Processes(double click), in the list that you get verify that the return code is 0.
Thanks & Regards,
Renjith.
