Description

(1) Create a Sharepoint repository connection
(2) Click on the Server tab
(3) Try to add a certificate by finding a valid cert and clicking the "Add" button

A 500 error is returned. The exception trace looks like this:

Caused by: java.lang.NullPointerException

.java:388)

It looks like the rendering flow is no longer the same, and therefore the certificate store is not loaded into the local variable that the processConfigurationPost() method is expecting to find it in.

The connector code can be rewritten for the connectors where this happens but frankly this will cause many of the connector UI's out there to break badly. Is there another way to address this?
