Hi!

In your process you have to model the inputs and outputs of each test. In your case, coudl be:
task1
input: -
output: Person object

task2:
input: Person object
output: Person object

task3:
input: Person object
output-

You should declare your Person object as process variable:
<itemDefinition id="_personItem" structureRef="org.test.Person" />
...
<property id="person" itemSubjectRef="_personItem"/>

When declaring inputs and outputs you should make reference to this process variable, for example
For input:
<dataInputAssociation>
           <sourceRef>person</sourceRef>
        <targetRef>_9_personInput</targetRef>
      </dataInputAssociation>

and for output:
      <dataOutputAssociation>
        <sourceRef>_8_personOutput</sourceRef>
        <targetRef>person</targetRef>
      </dataOutputAssociation>

This should help you:

Hope it helps,
