<div class="jive-rendered-content"><p>Hi all,</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>this is my first post here, since I'm pretty new with jbpm and bpm in general. Installation worked fine and trying one of the example processes is fine as well.</p><p>So I tried to set up my own process wich just consists of Start->script->user->script->end, to get a little "deeper" training. The code is (almost) the same compared to EvaluationExample2.</p><p>But I just wanted to complete 1 user task, no gateways or anything else. Long sentence short, it works fine ONCE. </p><p>Im using jBPM 6. Here's the code:</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>     </p><pre class="jive-pre"><code class="jive-code jive-java"><font color="navy"><b>public</b></font> <font color="navy"><b>static</b></font> <font color="navy"><b>void</b></font> main(String[] args) <font color="navy"><b>throws</b></font> Exception<font color="navy">{</font>

</code></pre><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>The error is the following: User '[UserImpl: 'user1']' was unable to execution operation 'Start' on task id 4 due to a no 'current status' match.</p><p>So everytime I:</p><p>          - change the string of employee (e.g. "user1" to "user2"), it works ONCE again, but the taskId is summating (every time I try to run, its getting taskId++;).
