Calculated fields with an empty DataMember aren't initialized correctly

I have requested a public fix, but it is decribed as 1.5.
As there is no 1.5 available, I need a fix for 1.4 immediately!

Hi Severin,

The bug fix will be included in the next maintenance update (v2012 vol 1.5). A current intermediate build still has the v2012 vol 1.4 signature, though. Once we publish the latest intermediate build, you will be able to integrate it into your application and verify that the bug fix is effective. We do not usually recommend including intermediate build assemblies into the production package. Every intermediate build passes our automated tests, but we do not test them thoroughly. Therefore, it is possible that an intermediate build contains other bugs, including critical ones.

As also the "main" release will be full of bugs. So no problems with intermediate builds.
This error is a real show stopper, and I need a solution now!
I'm knowing the problematic about intermediate builds, and it was no problem ever.

OK, Severin. Once we prepare and upload the appropriate hotfix build, you will receive an e-mail notification.
