Using 1.16.0. Didn't go further into it. Caused by: java.lang.NullPointerException org.apache.isis.viewer.wicket.model.models.ScalarModelWithPending$Util$1#setObject(ScalarModelWithPending.java:75) -- ScalarModelWithPending.java lines 74-76 -- if (LOG.isDebugEnabled()) { LOG.debug("setting to: " + adapterMemento!=null?adapterMemento.toString():null); } Thanks and regards Martin [0] https://en.wikipedia.org/wiki/Heisenbug --001a114af7ca78afe405641e1dd9--
