<div class="jive-rendered-content"><p>So when trying your suggestions:</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>I tried using a process variable to specify GroupId for a task. I would like to ask whether you have done this successfully; if so, I will try harder! At present it seems to fail. Note this is jBPM 5.2.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>So the name of the group to which I want to associate this task is "managers". I had specified GroupId as "managers" (without quotes) in the task definition and this worked as expected.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>I tried using a process variable to specify ActorId. This also clearly worked. Also I believe I found some JUnit test in the source distribution that exercises this.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>So I changed the GroupId specification to "#{managersGroup}" plus I defined a process variable with this name.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>To assign a value to this variable, I created a Script Node (that executes right after the process is instantiated) that assigns the value:</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p><span style="font-size: 8pt;"><p align="left">System.out.println(<span style="color: #008000; font-size: 8pt;">"** ** ** ** ** managers: "</span><span style="font-size: 8pt;"> + managersGroup + </span><span style="color: #008000; font-size: 8pt;">" ** ** ** ** ** ** **"</span><span style="font-size: 8pt;">);</span><p align="left"><div align="left"> </div></p></p></span><div> </div></p><p><span style="font-size: 8pt;"><p align="left">managersGroup = <span style="color: #008000; font-size: 8pt;">"managers"</span><span style="font-size: 8pt;">;</span></p></span><span style="font-size: 8pt;"><p align="left"><span style="font-size: 8pt;"><span style="font-size: 1;"><p>System.out.println(</p></span><span style="color: #008000; font-size: 8pt;">"** ** ** ** ** managers: "</span><span style="font-size: 8pt;"> + managersGroup + </span><span style="color: #008000; font-size: 8pt;">" ** ** ** ** ** ** **"</span> <span style="font-size: 1;">);</span></span></p></span></p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>I see the messages written to stdout that indicate the variable has this value assigned.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>However, when a member of the managers group looks at their task list, it is empty.
