How to set Token name?

[j.wozniakowski]

Hello,

I need to set Token name when it is created. Token class allows setting name only through the constructor (setter setName() is missing). Starting the process is done like this:

JbpmContext context = getJbmContext();
ProcessDefinition pd = context.getGraphSession().findLatestProcessDefinition(definition);
context.setActorId(Actor.instance().getId());
ProcessInstance p = new ProcessInstance(pd);
TaskMgmtInstance taskMgmtInstance = p.getTaskMgmtInstance();
context.save(p);
TaskInstance task = taskMgmtInstance.createStartTaskInstance();
task.start();
task.end();
context.save(task);
context.close();

but ProcessInstance creates Token with empty name!

I think the best solution would be another ProcessInstance constructor like this:

public ProcessInstance( ProcessDefinition processDefinition, String rootTokenName){ ... }

Is this a good idea? Feature request in Jira?

You can always get the root token. So it doesn't need a name.
For all other tokens you may create the name can be set in the constructor.

I think a setname method would be pretty useless...

As I said - I need to set root token name. This is a business requirement, not only for developers use.

Use the businesskey for this... this is new in jbpm 3.2 and introduced for relating processes to external data. You can then retrieve the processinstance based on this key and easily get the root token

Thank you. This works and solves my problem. :-)

HI! did you solve your problem of setting the name property in the token class/table? im asking because i cant set a token parent without setting a name, otherwise it will give me an error having to do with the children Map which uses the name field to build the Map with the children.
