<div class="jive-rendered-content"><p>Hi,</p><p>I've started using jBPM 5.3.0.Final. I want to use HumanTasks embedded in my application. So basing on thread:</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p><a class="" href="https://community.jboss.org/thread/162963?start=15&tstart=1">https://community.jboss.org/thread/162963?start=15&tstart=1</a></p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>I created my own LocalHumanTaskHandler where in constructor TaskServiceSession is created:</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>        TaskService taskService = new TaskService(emf, SystemEventListenerFactory.getSystemEventListener());</p><p>        taskSession = taskService.createSession();</p><p>        this.session=session;</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>ExecuteWorkItem method is taken from <span style="color: #445588; font-family: Consolas, 'Liberation Mono', Courier, monospace; font-size: 12px; font-weight: bold; background-color: #ffffff;">GenericCommandBasedWSHumanTaskHandler</span>. The only change is to invoke:</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>taskSession.addTask(task, content);</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>instead of:</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>client.addTask(task, content, new TaskAddedHandler(workItem.getId()));</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>I can work with HT in a way e.g.:</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>List<TaskSummary> taskList = wrapper.taskServiceSession.getTasksAssignedAsPotentialOwner("john", "en-UK");</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>wrapper.taskServiceSession.taskOperation(Operation.Complete, lastTask.getId(), "john", null, null, null);</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>It almost works correctly, task data is stored in DB but process instance is not updated after complete task. The problem is how can I register TaskEventHandlers. In <span style="color: #445588; font-family: Consolas, 'Liberation Mono', Courier, monospace; font-size: 12px; font-weight: bold; background-color: #ffffff;">GenericCommandBasedWSHumanTaskHandler</span> there is a method:</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p class="line" id="LC106" style="padding: 0 0 0 10px;"><span class="kd" style="font-weight: bold;">private</span> <span class="kt" style="color: #445588; font-weight: bold;">void</span> <span class="nf" style="color: #990000; font-weight: bold;">registerTaskEventHandlers</span><span class="o" style="font-weight: bold;">()</span> <span class="o" style="font-weight: bold;">{</span></p><p class="line" id="LC107" style="padding: 0 0 0 10px;">        <span class="n">TaskEventKey</span> <span class="n">key</span> <span class="o" style="font-weight: bold;">=</span> <span class="k" style="font-weight: bold;">new</span> <span class="n">TaskEventKey</span><span class="o" style="font-weight: bold;">(</span><span class="n">TaskCompletedEvent</span><span class="o" style="font-weight: bold;">.</span><span class="na" style="color: #008080;">class</span><span class="o" style="font-weight: bold;">,</span> <span class="o" style="font-weight: bold;">-</span><span class="mi" style="color: #009999;">1</span><span class="o" style="font-weight: bold;">);</span></p><p class="line" id="LC108" style="padding: 0 0 0 10px;">        <span class="n">TaskCompletedHandler</span> <span class="n">eventResponseHandler</span> <span class="o" style="font-weight: bold;">=</span> <span class="k" style="font-weight: bold;">new</span> <span class="n">TaskCompletedHandler</span><span class="o" style="font-weight: bold;">();</span></p><p class="line" id="LC109" style="padding: 0 0 0 10px;">        <span class="n">client</span><span class="o" style="font-weight: bold;">.</span><span class="na" style="color: #008080;">registerForEvent</span><span class="o" style="font-weight: bold;">(</span><span class="n">key</span><span class="o" style="font-weight: bold;">,</span> <span class="kc" style="font-weight: bold;">false</span><span class="o" style="font-weight: bold;">,</span> <span class="n">eventResponseHandler</span><span class="o" style="font-weight: bold;">);</span></p><p class="line" id="LC110" style="padding: 0 0 0 10px;">        <span class="n">key</span> <span class="o" style="font-weight: bold;">=</span> <span class="k" style="font-weight: bold;">new</span> <span class="n">TaskEventKey</span><span class="o" style="font-weight: bold;">(</span><span class="n">TaskFailedEvent</span><span class="o" style="font-weight: bold;">.</span><span class="na" style="color: #008080;">class</span><span class="o" style="font-weight: bold;">,</span> <span class="o" style="font-weight: bold;">-</span><span class="mi" style="color: #009999;">1</span><span class="o" style="font-weight: bold;">);</span></p><p class="line" id="LC111" style="padding: 0 0 0 10px;">        <span class="n">client</span><span class="o" style="font-weight: bold;">.</span><span class="na" style="color: #008080;">registerForEvent</span><span class="o" style="font-weight: bold;">(</span><span class="n">key</span><span class="o" style="font-weight: bold;">,</span> <span class="kc" style="font-weight: bold;">false</span><span class="o" style="font-weight: bold;">,</span> <span class="n">eventResponseHandler</span><span class="o" style="font-weight: bold;">);</span></p><p class="line" id="LC112" style="padding: 0 0 0 10px;">        <span class="n">key</span> <span class="o" style="font-weight: bold;">=</span> <span class="k" style="font-weight: bold;">new</span> <span class="n">TaskEventKey</span><span class="o" style="font-weight: bold;">(</span><span class="n">TaskSkippedEvent</span><span class="o" style="font-weight: bold;">.</span><span class="na" style="color: #008080;">class</span><span class="o" style="font-weight: bold;">,</span> <span class="o" style="font-weight: bold;">-</span><span class="mi" style="color: #009999;">1</span><span class="o" style="font-weight: bold;">);</span></p><p class="line" id="LC113" style="padding: 0 0 0 10px;">        <span class="n">client</span><span class="o" style="font-weight: bold;">.</span><span class="na" style="color: #008080;">registerForEvent</span><span class="o" style="font-weight: bold;">(</span><span class="n">key</span><span class="o" style="font-weight: bold;">,</span> <span class="kc" style="font-weight: bold;">false</span><span class="o" style="font-weight: bold;">,</span> <span class="n">eventResponseHandler</span><span class="o" style="font-weight: bold;">);</span></p><p class="line" id="LC114" style="padding: 0 0 0 10px;">    <span class="o" style="font-weight: bold;">}</span></p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>but I have no client so I have no possibility to register these events.
