----------------------------------------
Summary: Cast type (typeFilterOnCollection) not taken into account
while expanding a collection
Key: OLINGO-964
URL: https://issues.apache.org/jira/browse/OLINGO-964
Project: Olingo
Issue Type: Bug
Components: odata4-server
Affects Versions: (Java) V4 4.2.0
Reporter: Jacek Miłaczewski
Priority: Critical
Attachments:
0001-fix-proposal-for-cast-type-not-taken-into-account-wh.patch
When user want to expand collection of entities (e.g. 'Products') with casting
type of this collection to some subtype (''FeaturedProduct) and use property
from this subtype as navigation property to be expanded ('Advertisement'),
error occurs because of not taking into account this subtype in
ExpandParser.java code but use only superType instead.
Example url:
http://.../OData.svc/Categories(1)?$expand=Products/ODataDemo.FeaturedProduct($expand=Advertisement)
I attach a patch with proposal fix to illustrate what is going on and how it
should work in my opinion.
