Task and Phone Activity Created through the Social Pane CRM 2013

Hi there,

I have a plugin customization that updates the organization field on the activity
entity if the Regarding field has a parent organization. The plugin gets fired
on the PostCreate and looks for if the Regarding Object Id is populated and
then gets parent organization id and populates the activity entity. The plugin
works fine when creating Task, Phone from Activity Form but not from the Social
Pane on the Contact entity.  My plugin is looking for regardingobjectid
field. When Task or Phone Activities are created from the Social Pane it looks
like the regardingobjectid is not been passed in the CRM pipeline.

What am I
missing? Here is my plugin code

private
static string Customer = "regardingobjectid";

     private static string ParentCustomer =
"my_organizationid";

     public override void HandleAfterOpCreate()

     {

         try

         {

             if (!
(this.PluginExecutionContext.PrimaryEntityName.ToLower().Equals(Xrm.Task.EntityLogicalName)
||

                   
this.PluginExecutionContext.PrimaryEntityName.ToLower().Equals(Xrm.PhoneCall.EntityLogicalName)
||

                   
this.PluginExecutionContext.PrimaryEntityName.ToLower().Equals(Xrm.Email.EntityLogicalName)
||

                   
this.PluginExecutionContext.PrimaryEntityName.ToLower().Equals(Xrm.Appointment.EntityLogicalName)))

                 return;

             base.HandleAfterOpCreate();

             if (this.PluginExecutionContext.MessageName
== MessageName.Create)

             {

                 if
(this.InputTargetEntity.Contains(Customer))

                 {

                     var
id = this.OutputID;

                     var
customerId = ((EntityReference)this.InputTargetEntity.Attributes[Customer]).Id;

                   
 ActivityService.UpdateActivity(id, customerId, this.OrganizationService,
this.TracingService, this.PluginExecutionContext.PrimaryEntityName.ToLower());

                 }

             }

         }

         catch (Exception ex)

         {

           
 this.TracingService.Trace(this.ToString() + " {0}",
"Exception:  {0}", ex.ToString());

             throw;

         }

     }
