Whenever I try to add a new Connection, I get an Exception whose InnerException.Message is "Both objects being connected are missing".
When I step through my code, all the values resolve and are set as indicated in the connToInsert object, but the exception is thrown when the result is retrieved in the OnCreateConnectionComplete method.
I can verify that the Guid values are correct for the Task activity and the Account entity that I'm trying to connect. I can verify that the Task and Account LogicalName variables are set correctly. I can verify that there exists a ConnectionRole called "Activity" and that Task is one of the record types for which it is valid. I can verify that there exists a ConnectionRole called "Company" and that it is valid for the Account entity. And I can verify that the Guid values for these ConnectionRole entities are indeed the ones passed into the new Connection object I'm trying to create.
Has anyone seen this behavior before and, if so, how did you resolve the issue?
My code is as follows:
//pasted from within btnConnect_Click()
Connection connToInsert = new Connection();
connToInsert.Name = theItem.Company.Name; //string variable that resolves properly
connToInsert.Record1Id.Id = new Guid(_activity_id); //activity ID as class variable
connToInsert.Record1Id.LogicalName = _activity_typename; // "task"
connToInsert.Record1RoleId.Id = _activity_connectionRole_Id; // known connection role
connToInsert.Record1RoleId.LogicalName = "connectionrole";
connToInsert.Record2Id.Id = theItem.Company_ID; //Guid variable that resolves properly
connToInsert.Record2Id.LogicalName = "account";
connToInsert.Record2RoleId.Id = _company_connectionRole_id; //known connection role
connToInsert.Record2RoleId.LogicalName = "connectionrole";
_context.AddToConnectionSet(connToInsert);
_context.BeginSaveChanges(OnCreateConnectionComplete, connToInsert);
private void OnCreateConnectionComplete(IAsyncResult result)
{
try
{
_context.EndSaveChanges(result);
Connection createdConn = result.AsyncState as Connection;
lblStatus.text ="Created new connection";
}
catch(SystemException se)
{
throw;
}
}
Thanks,
John

I have the same question (0)I have resolved this issue.
In Silverlight, the EntityReference entity has only one constructor, with no parameters. That is why I was assigning values directly to the Id fields' properties. Doing the following instead allowed the Connection to be created:
EntityReference record1Id = new EntityReference();
record1Id.Id = new Guid(_activity_id);
record1Id.LogicalName = _activity_typename;
connToInsert.Record1Id = record1Id;
And so forth for Record2Id, Record1RoleId, and Record2RoleId.
