hi ！
*when i put variable in map(data), my variableinstancelog table is nothing,*
public void completeTask(long taskId, Map<?, ?> data, String userId, Map<String, Object> results )
throws InterruptedException {
connect();
BlockingTaskOperationResponseHandler responseHandler = new BlockingTaskOperationResponseHandler();
client.start(taskId, userId, responseHandler);
responseHandler.waitTillDone(2000);
responseHandler = new BlockingTaskOperationResponseHandler();
ContentData contentData = null;
if (data != null) {
ByteArrayOutputStream bos = new ByteArrayOutputStream();
ObjectOutputStream out;
try {
out = new ObjectOutputStream(bos);
out.writeObject(*data*);
out.close();
contentData = new ContentData();
contentData.setContent(bos.toByteArray());
contentData.setAccessType(AccessType.Inline);
} catch (IOException e) {
e.printStackTrace();
}
}
client.complete(taskId, userId, contentData, responseHandler);
}
*but i add this code ,*
*when i put variable in map(+results+) ,it work,*
+ BlockingGetTaskResponseHandler responseHandlerGetTask = new BlockingGetTaskResponseHandler();+
+ client.getTask(taskId, responseHandlerGetTask);+
+ responseHandlerGetTask.waitTillDone(1000);+
+ Task task = responseHandlerGetTask.getTask();+
+ ksession.getWorkItemManager().completeWorkItem(+
+ task.getTaskData().getWorkItemId(), *results*);+
*I I do not understand, I see other people are like first code. I used jBPM5.4. Thanks For any help in adcance.*

I need to get the tasks by status and then start them.
But at some times while retrieveing the tasks im getting the started process id as well and thats in where im getting this exception.
org.jbpm.task.service.PermissionDeniedException: Server-side Exception: User '[User:'admin']' was unable to execution operation 'Start' on task id 287271 due to a no 'current status' match
at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method)
at sun.reflect.NativeConstructorAccessorImpl.newInstance(NativeConstructorAccessorImpl.java:39)
at sun.reflect.DelegatingConstructorAccessorImpl.newInstance(DelegatingConstructorAccessorImpl.java:27)
My mina task handler is running in jboss and the application uses its client to the task operations.
Retrieveing tasks by status:
BlockingTaskSummaryResponseHandler resHandler = new BlockingTaskSummaryResponseHandler();
List<Status>statusls=new ArrayList<Status>();
statusls.add(Status.Reserved);
client.getTasksAssignedAsPotentialOwnerByStatus("admin",statusls, "en-UK", resHandler);
Starting the task:
BlockingTaskOperationResponseHandler responseHandler = new BlockingTaskOperationResponseHandler();
client.start(taskId, userId, responseHandler);
*Is there any thing to do with hibernate or what should i take care to eliminate this replication.?*

[jBPM] - Custom WorkItemHandler - variables being converted to String
by Victor Tatai

"Custom WorkItemHandler - variables being converted to String"
To view the discussion, visit: https://community.jboss.org/message/803788#803788
--------------------------------------------------------------
Hello,
I am in the process of implementing a custom WorkItemHandler which allows calling Spring bean methods. It is all working so far, except when I use an expression for setting a parameter such as:
<dataInputAssociation>
<targetRef>_3_Param3Input</targetRef>
<assignment>
<from xsi:type="tFormalExpression">#{processData}</from>
<to xsi:type="tFormalExpression">_3_Param3Input</to>
</assignment>
</dataInputAssociation>
(#{processData} is actually a java.util.Map)
then in my custom WorkItemHandler, when I do WorkItem#getParameters() for that parameter, it is there, but it is converted as a String - i.e., it is not a Map anymore.
I was actually able to debug and found this bit of code inside jBPM's WorkItemNodeInstance#createWorkItem():
Object variableValue = variableScopeInstance.getVariable(paramName);
String variableValueString = variableValue == null ? "" : variableValue.toString();
replacements.put(paramName, variableValueString);
I was actually able to see that variableValue is the map I am expecting, so the variable exists and is being located correctly. What seems odd to me is the conversion from variableValue to variableValueString by calling 'variableValue.toString()'.
Perhaps I'm doing something wrong in my WorkItemHandler, but I can't really see what. Please help!
For reference, my wid file is:
import org.drools.process.core.datatype.impl.type.StringDataType;
import org.drools.process.core.datatype.impl.type.ObjectDataType;
[
[
"name" : "Spring",
"parameters" : [
"Bean" : new StringDataType(),
"Method" : new StringDataType(),
"Param1" : new ObjectDataType(),
"Param2" : new ObjectDataType(),
"Param3" : new ObjectDataType(),
"Param4" : new ObjectDataType(),
"Param5" : new ObjectDataType(),
"Param6" : new ObjectDataType(),
"Param7" : new ObjectDataType(),
"Param8" : new ObjectDataType(),
"Param9" : new ObjectDataType()
],
"displayName" : "Spring",
"icon" : "icons/spring.png"
]
]
Thanks for the help,
Victor
