I got about 1500 taskInstances in my DB applied to a single user.
I'm extracting all these TaskInstances via
jbpmCtx.getTaskList("actorId");
|
Then I'm accessing the contextVariables of the according contextInstance by
Token tk = taskInstance.getToken();
| ProcessInstance pi = tk.getProcessInstance();
| ContextInstance ci = pi.getContextInstance();
| ci.getVariable("nameOfVariable");
|
Problem is, that the ProcessInstance, ContextInstance and Variables are fetched
non lazy by Hibernate. Thus for each access to a Set of variables a new query
is executed. It takes ca. 50 sec to retrieve all the results i need, wich is
much too long!
Currently I'm trying a workaround based upon HQL like this:
List<Object> list =
| s.createQuery("select ti, tk, pi, vi " +
| "from TaskInstance ti " +
| "join ti.token tk " +
| "join tk.processInstance pi, " +
| "VariableInstance vi " +
| "where vi.token=tk").
| list();
This is rather ugly...
Does anyone know, or can anyone think of another, better way to initialize the
Variables of the according ContextInstance of a TaskInstance.?
By the way...
Shouldn't the global variables of a Token be passed through to the local
variables of a TaskInstance? Currently they are not... Is this a bug?
