Hi,
I have written a birthday plugin, which fills 3 new fields birth day, birth month, birth year on create or update of a contact.
The plugin is registered via plugin registration tool as pre-operation for create and update contact. For the update step a pre-image for the "owningbusinessunit" is added.
The plugin runs fine, when I manually create or update a contact in the CRM 2011 GUI. But for all contacts created or update via the web service (daily import) the plugin fails with following error:
06-04-2015 13:09:01,883 ERROR [ 3] Unexpected exception from plug-in (Execute): BirthdayPlugin.BirthdayField: System.NullReferenceException: Object reference not set to an instance of an object. (File:131)

06-04-2015 13:09:01,884 ERROR [ 3] Plugin Trace:
[BirthdayPlugin: BirthdayPlugin.BirthdayField]
[xxxx: BirthdayPlugin.BirthdayField: Update of contact]
At first I thought it is related to this line in my code:
IOrganizationService service = serviceFactory.CreateOrganizationService(context.UserId);
Because the contact is created/updated by the "SYSTEM" user, so probably no UserId is being returned. But now I changed the plugin to run as a specific user instead of calling user and the problem still persists.
I would be grateful for any help.
thx in advance Thomas
