After the login page (cookie monster/bert/grover/ernie) of the starter's kit, I
get the following error :
javax.servlet.ServletException: Cannot get value for expression
'#{homeBean.latestProcessDefinitions}'
I managed to switch to a mysql database. I tested the connection and it seems
to work fine.
I know the jbpm login page can access the database because i added a new user,
and it appeared within the list of users : cookie monster / bert / grover /
ernie
But when it starts to look for process definition in the database, it gives me
this error.
Any clues?ideas?
Thanks in advance..
Mennen
