Update Value of an Attribute on Resulting Objects (type EPMDocument) through Expression Robot

[PA_11085333]

Hello! I am looking for some help with updating the value of an attribute that exists on resulting objects of a change activity through the use of an expression robot in the workflow of the change activity. The resources I've been able to find all seem to call out the object that's having its attribute modified as the primarybusinessobject, so where I am having trouble is calling to the resulting objects while the change activity is the primarybusinessobject of the workflow.

I tried the following, but had the error returned "WTChangeActivity2 cannot be converted to FormDataHolder"

wt.change2.WTChangeActivity2 changeTask = (wt.change2.WTChangeActivity2) primaryBusinessObject;

java.util.Vector results = com.ptc.windchill.enterprise.changeable.ChangeableDataFactory.getResultingObjects(changeTask);

Could you share some more of the code you're trying?

Essentially I think you need to navigate from the ECN to the Resulting Objects. A first step would be this: https://www.ptc.com/en/support/article/CS55955?source=search

You can use this code snippet

ChangeActivity2 changeActivity = (ChangeActivity2) primaryBusinessObject;
QueryResult theChangeablesAfterResult = ChangeHelper2.service.getChangeablesAfter(changeActivity,
false);
while (theChangeablesAfterResult.hasMoreElements()) {
Object element = theChangeablesAfterResult.nextElement();
if (element instanceof ChangeRecord2) {
changeRecord = (ChangeRecord2) element;
Changeable2 theChangeable = changeRecord.getChangeable2();
