[jira] Commented: (CAY-1077) ObjRelationship Mapping Dialog Improvements

["Andrey Razumovsky (JIRA)" <de...@cayenne.apache.org>]

Andrey Razumovsky commented on CAY-1077:
----------------------------------------

Agreed. Actually I think this must be the same as 'Prefetches' browser, only using DbRels instead of ObjRels. I even think that 'Target' field in Inspector must be made read-only, because chain of relationships is determining it anyways. Auto-suggesting of relationships is cool, but not needed if we can choose them in a couple of clicks (and all rels would be seen at once, not in dropdown). 
And Inspector must be able to be opened even if to Target was set, since it's a bit irritating to choose end destination and only then to complete all the path.

> The biggest complaint about the ObjRelationship mapping dialog is that it is often unclear how it operates, especially to the new users. I.e. empty list of DbRelationships is displayed as a white area, not giving any hints on what needs to be done to map a relationship. So that's confusing. Same thing when you add 1 path component, there is no hint that you can chain more path components for the flattened relationship.
> At the minimum we may just add some hint text ("Select next DbRelationship" in grey over the next available dropdown), but ideally we should implement a path browser, similar to how the SelectQuery prefetch and ordering browsers operate (and similar to how OS X Finder does).
