Workflow Map and dependent relationship

Former Member
Former Member
I am trying to validate the proof-of-concept for a parser designed for automated integration of process models. I would like to use a server-side method in C#. Creating new workflow maps works so far. Unfortunately, I already fail in a basic functionality. I want to set an activity template as a child relation to a workflow map. Here is my previous code:
Innovator inn = this.getInnovator(); Item workflow = inn.getItemById("Workflow Map","AAE3732B971C4397917669FC46576DC8"); string id = getNewID(); // Create new instance of Relationship ItemType Item newWMA = inn.newItem("Workflow Map Activity","add"); newWMA.setProperty("source_id", "AAE3732B971C4397917669FC46576DC8"); Item relatedItem = newItem("Activity Template","add"); newWMA.setRelatedItem(relatedItem); workflow.addRelationship(newWMA); relatedItem.apply(); return this;
Unfortunately the execution always results in the following error code:
Dependent Activity Template cannot be create: source item not found.
The ItemType Activity Template is set to "dependent". I assume that the error is related to this. Many thanks for the help in advance. Greetings Rik

    Hi Rik, There doesn't appear to be an easy way through the REST API alone to get the id of an Item property that does not have a data source. I'll file this internally to be added in a future release. I understand that this functionality isn't critical for your use case, but I did discover a solution that would allow you to get the ID as expected. You can create a server method with code like the sample below. 
    string wmpId = this.getProperty("wmp_id");
Item wmp = this.newItem("Workflow Map Path", "get");
wmp.setID(wmpId);
return wmp.apply();
    You can then call this method through the REST API and pass in the ID of the Workflow Map Path you want to get like: 
    POST host/.../method.GetWorkflowMapPath
{
"@odata.type": "host/.../$metadata,
"wmp_id": "654FF9665F2F415683722C6AA698A1DE"
}
    The body of the response should contain the related_id as expected. Chris
