Multivalue DN validator throws an invalid cast error

Matthew Clark 12 years ago • updated by anonymous 9 years ago • 1

When attempting to create the correct value during an export, a multivalue DN generator field throws a cast exception:

Unable to cast object of type 'Unify.Framework.MultiValue`1Unify.Framework.StringValue' to type 'System.Collections.IEnumerable'.

Source value in this case is a single entry: CN=Administrator,DC=UNIFY2010DEMO. The object attempting a cast is a MultiValue<StringValue> as parsed by the LDIF handling.

Changed handling of multivalues such that the enumerable is passed through to the validator. Tested for multivalue attributes, and confirmed single value field updates haven't regressed. Issue resolved and closed.
