Modelling real time complex workflows...

Question

i am trying to create a workflow...
the scenario is like this...a user fills in a project initiation form...
it goes to a group called submission_group for review...any member from that group may approve or reject it...
if it is approved, it will be forwarded to the project manager
the project manager just has to fill in some comments and forward it to executive comittee...
project manager does not have rejection rights on the project...
once executive committe acts on the form the executive committe can reject the project also...
then it goes to two people in parallel one of which has rejection rights.
how to model this kind of workflow...where some people have reject rights but some people do not have...
I tried modelling all human tasks as individual task and using "include task history" functionality...but that throws up lots of compilation problems....
has anybody modelled such a workflow with bpel...
appreciate ur help

Answer 1

i have successfully built single approver, sequential approver workflows etc...
here is the sample workflow that i created, i am attaching the .bpel source and the source for human_task1 and human_task2..the human_task2 is using "include task history " from human_task1...the compilation errors are also given in the end of this mail
.bpel source
