Greetings to the community! I am using
Alfresco 6.0.0 Community edition
with the embedded
Activiti
engine. I am creating many kind of different processes/tasks through .bpmn files and now I would like to
somehow achieve the following scenario
:
1) Deploy a .bpmn file with 2
usertasks
(
usertask1 -> seqflow -> usertask2
).
2) While being on the first task I set/update a process variable and set to it a JSON formatted String (f.e "
{ id: '100', name:'X'}
" )
My question is
if there is any possible way to parse that JSON (f.e to obtain the 'id' or the 'name' values ) inside the bpmn??
I want to achieve this inside the usertask2, is there any possible way? Maybe something in the
ScriptTaskListener
or any other listener?? Any help would be greatly appreciated.
Thanks :)
Here is the usertask
<userTask id="task2" name="${nameSetOnTask1}"
activiti:formKey="wf:adhocTask">
<documentation> Second task </documentation>
<extensionElements>
<activiti:taskListener event="create" class="org.alfresco.repo.workflow.activiti.tasklistener.ScriptTaskListener">
<activiti:field name="script">
<activiti:string>
var json = execution.getVariable('json') <!-- this is the string with json value -->
</activiti:string>
</activiti:field>
</activiti:taskListener>
</extensionElements>
</userTask>
I managed to parse the Json String using the Javascript's JSON.parse
function
<activiti:string>
var json = execution.getVariable('json')
var jsonObject= JSON.parse(json) ;
var idValue = jsonObject.id
</activiti:string>
