Sorry for my ugly english at first.
I can't decide my problem for a few days. I am working on web application
similiar to native jbpm demo app.
I am using this code to load taskInstance and save variables (little
simplified):
| JbpmContext jbpmContext=null;
| try
| {
| jbpmContext=createJbpmContext();
| long taskId=0;
| String taskIds=request.getParameter("taskId");
| if(taskIds!=null)
| {
| try
| {
| taskId=Long.parseLong(taskIds);
| }
| catch(NumberFormatException e)
| {
| }
| }
| TaskInstance
taskInstance=jbpmContext.getTaskMgmtSession().loadTaskInstance(taskId);
| List
varAccesses=taskInstance.getTask().getTaskController().getVariableAccesses();
| if(varAccesses!=null)
| {
| for(Iterator
iter=varAccesses.iterator();iter.hasNext();)
| {
| VariableAccess
varAccess=(VariableAccess)iter.next();
| if(varAccess.isWritable())
| {
| String name=varAccess.getVariableName();
| String
value=pRequest.getParameter(name);
| if(value==null||value.length()==0)
| {
| if(varAccess.isRequired())
| {
| throw new
UserError("parameter_required");
| }
| }
| else
| {
|
taskInstance.setVariable(name,value);
| }
| }
| }
| }
| //marker 1
| taskInstance.end(request.getParameter("transition"));
| //marker 2
| }
| finally
| {
| jbpmContext.close();
| }
|
Before line marked as "marker 1" all seems to be ok, variable updates theirs
values, if i display it to System.out i see, that values is changed. But after
i end task instance if variable was setted before, in some earlier task, then
it backs old value again.
For example: variable "test" has value "first value" which was setted in some
previouse task node. In current task node i am trying to update it to "second
value" all seems to be good until i end task node. Before i end it i have a
"second value" as a value of variable "test", but after i end task value
returns to previous one and has "first value" as a value.
Please explain what am i doing wrong?
Thank you.
