How to use the java api to add WTDocument to the "Change Summary" table in Change Notice?

[VladiSlav]

I have code to output "Change Summary" object types from a Change Notice
But I do not know how to add more objects to this table, for example, WTDocument

public static void printChangeAfter(WTChangeOrder2 wtChangeOrder2) {
        try {
            QueryResult result = ChangeHelper2.service.getChangeActivities(wtChangeOrder2);
            while (result.hasMoreElements()) {
                WTChangeActivity2 activity = (WTChangeActivity2) result.nextElement();
                QueryResult res = ChangeHelper2.service.getChangeablesAfter(activity);

                while (res.hasMoreElements()) {
                    WTObject object = (WTObject) res.nextElement();
                    System.out.println(object.getType());
                }
            }
        } catch (WTException e) {
            System.out.println("error " + e.getMessage());
        }
    }

You can use instanceof to know if object is WTDocument, WTPart etc 

if(object instanceof WTDocument){
WTDocument doc = (WTDocument)Object;

}

You can't add any object to the change summary table. This is just the summary of all the change tasks (change activities). You need to add them to a single change task

Vector partVec = new Vector();
partVec.addElement(part); //assuming you have the WTPart object 
partVec = ChangeHelper2.service.storeAssociations(ChangeRecord2.class, task, partVec); //task is Change Activity object
ChangeRecord2 resulting_data = (ChangeRecord2)partVec.firstElement();
resulting_data.setDescription("ChangeRecord2 and a Part");
partVec = ChangeHelper2.service.saveChangeRecord(partVec);

BjoernRueegg ,thank you very much, your code works as I wanted

[VladiSlav]

BjoernRueegg ,please tell me if you have a code to remove objects from the request

[BjoernRueegg]

You need find the link and delete the link.

Use the Helper class 

ChangeHelper2.service.

and than the method you need. If you use the method e.g.

ChangeHelper2.service.getChangeablesAfter(changenotice, false);

then you will receive the links and not the objects. Iterate thru the result and delete the link you don't need anymore.
