While try to open Entity Inspector of EntityB, the code in onBeforeDetach triggered below error:
Entity Inspector Error : IllegalStateException: Cannot get unfetched attribute [state] from object xx.entity.EntityA-c7474599-8640-b39c-49d2-2ecae289e449 [managed]
I try to change fetchType to (fetch = FetchType.EAGER), but still got same error.
I found that in EntityInspectorBrowse.java, in method createView(), it will use minimal view for association or composition relationship. In this case, it will not load extra properties. As a workaround, I added State property to entity @NamePattern to force State property loaded in minimal view make this exception gone. It’s your call to decide if this is a bug.
case ASSOCIATION:
case COMPOSITION:
if (!metaProperty.getRange().getCardinality().isMany()) {
View minimal = metadata.getViewRepository()
.getView(metaProperty.getRange().asClass(), View.MINIMAL);
View propView = new View(minimal, metaProperty.getName() + "Ds", false);
view.addProperty(metaProperty.getName(), propView);
}
break;
