Error description
The current REST API (for firefox) and image generation (for IE) code didn't handle the link control point properly. Depending on the number of control points in the link, it might cause an IndexOutOfBoundsException when determining the link label position. The exception in the Process Center Log: com.ibm.bpm.rest.impl.ilogdiagram.bpd.BPDILOGVisualResource getProcessInstancesForILOGDiagram Index: -1, Size: 0 java.lang.IndexOutOfBoundsException: Index: -1, Size: 0 at java.util.ArrayList.get(ArrayList.java:352) at com.ibm.bpm.rest.impl.ilogdiagram.LinkLabelPositionHelper.setLab lePosition(LinkLabelPositionHelper.java:20) Also when the link is across multiple swimlanes in a BPD,the bendpoints calculation is wrong, since the current code use the relative position for the x and y of control point, ILOG API expects absolute position when a link is cross swimlanes.

Problem conclusion
Changed the transformer from BPD (and TWProcess) to ILOG visual model so that it can calculate bendpoints properly when the control points are used. Problem is fixed in interim fix available in Fix Central. Problem is also fixed in future releases.
