How to change default claim and complete behavior of Tasks?

If have understood correctly,When a task is assigned to a group it appears in the Inbox of all users in that group. Now if anyone belonging to that group logs in and claims that task, it will disappear from the task list of all other users in that group. And when that user completes the task, it wil

sorry, my english is very poor.
I hope you can understand my words.

i think…
You can try to use Multi-instance (for each).

like this:


<userTask id="id" name="name" activiti:assignee="${assignee}">
    <extensionElements>
        <activiti:taskListener event="create" class="com.test.bpm.listener.CreateListener"></activiti:taskListener>
        <activiti:taskListener event="complete" class="com.test.bpm.listener.CompleteListener"></activiti:taskListener>
     </extensionElements>
     <multiInstanceLoopCharacteristics isSequential="false">
        <loopDataInputRef>assigneeList</loopDataInputRef>
        <inputDataItem name="assignee"></inputDataItem>
        <completionCondition>${beFinished.equals("true")}</completionCondition>
     </multiInstanceLoopCharacteristics>
</userTask>

in its complete event,you can make a rule to decide what time this userTask will be finished.
like this: its my rule ,when submit or reject count > a number, finish the task


String transition = (String) delegateTask.getVariable("transition");
int nrOfInstances = (Integer) delegateTask.getVariable("nrOfInstances");
int submitCount = (Integer) delegateTask.getVariable("submitCount");
int rejectCount = (Integer) delegateTask.getVariable("rejectCount");
int percent = (Integer) delegateTask.getVariable("percent");

if (transition.equals("submit")) {
 submitCount++;
 delegateTask.setVariable("submitCount", submitCount);
} else {
 rejectCount++;
 delegateTask.setVariable("rejectCount", rejectCount);
}
if (submitCount > nrOfInstances * Percent / 100 || rejectCount > nrOfInstances * Percent / 100)
 delegateTask.setVariable("beFinished", "true");
else
 delegateTask.setVariable("beFinished", "false");

and use this, you must make a Exclusive gateway after the task, because the Multi-instance(isSequential = "false") seem to include a Parallel Gateway.
if you don't, when Multi-instance(isSequential = "false") be finished , it will take all the OutgoingTransition.

sorry , my english is very poor. I finished this words with the help of google translation…

Did it work for you?
Are you able to create a scenario for the voting with activiti (with or without using multi-instance)?
