Hi phanlesang, One thing you can try is ODE Instant Management service to check whether the variable "detailIndex" is modified in a loop. During the startup of ODE it deploys a Management service which can be used to monitor the instance variables like "detailIndex".
You can use REST as follows To get the instance information use (iid=instance id) - http://localhost:8080/ode/processes/InstanceManagement/getInstanceInfo?iid=XXXX To get variable information use (sid=scope id , varName=variableName) - http://localhost:8080/ode/processes/InstanceManagement/getVariableInfo?sid=YYYY&varName=detailIndex Hope this will help Cheers, Denis Weerasiri http://ddweerasiri.blogspot.com On Tue, Jul 14, 2009 at 6:09 AM, phanlesang <[email protected]> wrote: > > Hi, > I've just tested an example using while loop.
