Hi everyone,

I am new to BPM world so I am starting to have interest with open source BPM solutions including jBPM of course  ;) 
Before dealing with complex business processes, I am starting playing with the Sample Demo but encounter some problems.

I succeed in executing  the demo under eclipse till complete process completion (john + mary Start / Complete jobs) so no problem.
I am playing now with the jBPM console to do the same :
1- log in with krisv and start a new Evaluation process
2- able to see in Personal Task the task just started and click on View to Complete
3- log out
4- log in as john but impossible to get any task displaying in john's Personal Task View even with clicking on Refresh button...
5- log out
6- log in as mary but same as step 4. In the Messages log area i always have a "[INFO ] Loaded 0 tasks"
7- log out
8- log in as krisv, delete the process instance running and start a new one and now no Personal Task displaying with krisv  :(  
In the log area i have :
2012-07-26 11:30:58,217 [DEBUG] GET:  http://localhost:8080/gwt-console-server/rs/tasks/krisv http://localhost:8080/gwt-console-server/rs/tasks/krisv

2012-07-26 11:31:18,277 [INFO ] Loaded 0 tasks

or sometimes

2012-07-26 11:18:53,649 [INFO ] Loaded 0 tasks

Any idea on what's going wrong or what i am doing wrong actually?

I am testing with the jbpm-5.3.0.Final-installer-full version.
