Hi Erik, strangely we had the same symptoms when working on the coming 2.0.0-M1 release. We tracked it down to the fact, that Isis' datanucleus extensions don't get installed during bootstrapping.
Would be interesting to see, whether our current workaround [1] (to copy over 2 files into your domain code) solves the issue. (Please let us know!) * /plugin.xml * /META-INF/MAINFEST.MF As of version 1.16.x these files are in the isis-core-runtime jar file of the release. Cheers Andi [1] https://issues.apache.org/jira/browse/ISIS-1902 On 2018/03/14 08:35:14, Erik de Hair <[email protected]> wrote: > Hi, > > I'm having troubles with Blob fields after upgrading to Apache Isis > 1.16.2 (not sure if this was also the case for 1.16.[0-1]).
