Null reference exception when viewing individual entities in the entity search

Matthew Clark 12 years ago • updated by anonymous 8 years ago • 3

When attempting to view some individual entities in the entity search, I received the following error:

System.NullReferenceException: Object reference not set to an instance of an object.
at Unify.Connect.Web.EntitySerializer.<>c_DisplayClass5.<EntityDisplayValues>b_2(GroupedNameValueCollectionKey valueKey) in c:\workspaces\DEV\IdentityBroker\Source\Studio\Unify.Connect.Web\Extensions\Entity\EntitySerializer.cs:line 45

The first 20 entities do not seem to exhibit this behaviour and they correctly display the entities. Changing the page size of the entity search does not seem to alleviate this behaviour.

The values in the entity do not appear to affect this behaviour. Example values of an entity that displays correctly:

The skip/take was being applied on the search for the entity to view, which meant that anything past the Default Skip/Take wouldn't be found.

Reassigned for confirmation of completion.
