[jira] [Closed] (ISIS-2649) [WON'T FIX] Regression: ObjectSpecification Predicates isEntity() and isViewModel() are always false when abstract
[ https://issues.apache.org/jira/browse/ISIS-2649?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Andi Huber closed ISIS-2649.
----------------------------
Resolution: Won't Fix
For non-scalar (collection) types, the meta-model inspects the generic type parameter or the type-of attribute if found within associated annotation. This makes the ObjectSpecification for the - as we call it - element type of the collection.
Now this is the one and only binding contract, for various framework supported areas:
UI Table Rendering (what columns should appear), RO-Viewer (what type upcast to use), Single/Multi Choice Providers (what title to use), there might be more.
On the other hand seems not relevant for Command/Execution-publishing and Change Tracking.
That said, I have a feeling, there is no quick and easy fix.
Can always reiterate if fresh ideas pop up.

> the {{ObjectBulkLoader_builtinHandlers.BulkLoadEntity}} could just handle the abstract types as well
> the {{isHandling(ObjectBulkLoader.Request objectQuery)}} method should probably just ask if the spec has an EntityFacet, independently of the BeanSort
