Can't import data types - NullReferenceException

[westaj]

Hi Kevin. I'm encountering the following with uSync8 and Umbraco 8.

Import of new data types fails with NullReferenceException; please see stack trace below. Report view shows 0 changes listed for these problematic types. If I create a data type with the same name, so the sync becomes an update, the import works fine. Issue is specific to data types.

Umbraco 8.0.0-alpha.58.2266
USync8 8.0.0-alpha61

Woot - first off you deserve some kind of award for trying this out.

the world of Umbraco 8 is fast moving, I know for instance that uSync 8 is in fact broken on the latest nightly builds something has moved about, but I will certainly look at this and see if I can track it down and fix it -

thanks.

Fixed in the latest alpha 2482 release - but you will almost certainly need to be running Umbraco Alpha.2482 for it to work.
