Writing a custom method that accesses attributes from the object in a business process' package.

I am trying to implement a custom method that can be used with a business process. The method should be able to get the content of the object in the process package.

First, I overrode the doTask method of the WorkflowActivity class:

@Override

protected int doTask(IDfWorkitem workitem, IDfProperties activityProperties, PrintWriter printWriter)

throws Exception {

Then I get all the attachments associated with this activity:

IDfCollection attachmentCollection = workitem.getAttachments();

IDfDocument attachmentDoc = null;

I search the collection of attachments for the attachment I want, then cast it to IDfDocument:

while (attachmentCollection.next())

{

IDfWorkflowAttachment attachment = (IDfWorkflowAttachment)attachmentCollection;

IDfType attachmentType = attachment.getType();

if (attachmentType.getName().equals("dl_model"))

{

attachmentDoc = (IDfDocument)attachment;

}

Is this the correct approach? Or is there a better way?

Hi Derrick,

Someone is looking into this - hope to get back to you soon.

Derrick,

Are you content objects in a package or are the attachments? There is a difference and your code addresses attachments. To access objects in a package, do something like this:

// get the package

IDfCollection col = workitem.getPackages(null);

                // loop through packages
                while (col.next()) {

                       // check for our package
                       if (col.getString("r_package_name").equalsIgnoreCase(<the name of your package defined in Process Builder>)) {
                           pkg = (IDfPackage) session.getObject(col.getId("r_object_id"));
                           break;
                       }
                }
                col.close();

// get the object you want

IDfSession session = pkg.getSession();
int compCnt = pkg.getComponentIdCount();

            // look through package looking for component
            for (int i=0; i<compCnt; i++) {
                IDfSysObject sObj = (IDfSysObject) session.getObject(pkg.getComponentId(i));

                // check for out type of component
                if ( (sObj.getTypeName().equalsIgnoreCase(<the object type you are looking for (e.g., dm_document)> )) ||
                        (sObj.isInstanceOf(<the object type you are looking for (e.g., dm_document)>)) ) {
                    compId = sObj.getObjectId();
                    break;
                }

sObj is now the obj you want to operate on.

I thought attachments were added to the package automatically when starting workflows?

When I double-click the task in the Inbox of DA, I see my object underneath the Package I created for the workflow. The attached screenshot should explain things.
