Error when creating new Association Entity
Posted: 02 Jul 09 9:43 AM

Basically I am creating a new Contact and an Association, when I hit the save button it works fine it saves the new Contact and the Association but right after a dialogbox is displayed, it reads :
Exception has been thrown by the target of an invocation.:
The argument component cannot be null. Parameter name: component
then I close the "Add" form and I can see that all information was inserted successfully, this is my code:
IC_EmployeeDetails EmployeeDetails = form.WorkItem.Services.Get().GetEntity() as IC_EmployeeDetails;
IContact contact = (IContact)form.CurrentEntity;
contact.Account = EmployeeDetails.Contact.Account;
contact.AccountName = EmployeeDetails.Contact.AccountName;
contact.Type = "typehere";
contact.Save();
IAssociation association = EntityFactory.Create();
association.BackRelation = "Dependent";
association.ForwardRelation = "Beneficiary";
association.FromId = Convert.ToString(EmployeeDetails.Contact.Id);
association.ToId = Convert.ToString(contact.Id);
association.BackNotes = null;
association.IsAccountAssociation = false;
contact.Associations.Add(association);
contact.Save();
association.Save();
If I remove the code where it is saving the Association Entity the error is not displayed anymore.
Any Ideas ?
Thanks

I typically save the child object before assigning it to the Parent collection. Try the following:
association.Save(); 'While in debug, stop after the save and see if the record made it into the Database.
'Then add it to the Contact's collection:
contact.Associations.Add(association);
'Unless you have changes to preserve at the Contact level, I don't think that you need to invoke a Contact.Save()
contact.Save(); 'Try skipping this step on the debugger and see if that clears the error while adding the association to the grid and the DB. |

I moved association.Save(); as suggested, just after this was executed I checked the DB and the record was there, then I added it to Contact's collection (and also tested not adding it to the collection), I removed contact.Save(); but I am getting same error.

Re: Found out - Error when creating new Association Entity
Posted: 07 Jul 09 8:49 AM

I got it working, I found out the problem, right after I save the entity I am trying to use one of the Parent Properties (Relationship) but this is null, it is after page does some auto-refresh that the entity loads the data in the Parent Properties, right now I am just making sure "property != null" then use it.
Is there any way to have the entity to refresh itself after being saved ?
