Karthick Sankarachary commented on ODE-536:
-------------------------------------------
Okay, in that case, can you please check out revision 750103? It performs
certain additional sanity checks that just might resolve your issue. In case it
doesn't, can you attach snippets of the BPEL file(s) that you think might be
involved?
