[rules-users] How to access process variables within a work-item (human task)

[Vijay K Pandey]

That will not register the process variables - its there to pass the variables data.

You can click on the process diagram in eclipse - go to properties "view" - and look for the "Variables" property. It's here that you have to register your process variables.

Hi,

I don't understand what you mean ?

I thought with

ksession.startProcess(processName, processVariables);

they are registered.
