---------------------------------------
Summary: EntityUUID - non-unique temp key
Key: OLINGO-1325
URL: https://issues.apache.org/jira/browse/OLINGO-1325
Project: Olingo
Issue Type: Bug
Components: odata4-ext
Affects Versions: (Java) V4 4.5.0
Reporter: Frederik Zimmer
We are using ext-proxy and a deep insert which produces incorrect results when
having many related entities. The reason for this is that in the class
EntityUUID for new entities a tempKey is computed like this
this.tempKey = (int) (Math.random() * 1000000);
which for many newly created entities causes collisions so that two new
different entities are considered equal by the equals method.
I think the whole point of the tempKey is to make new entities unique as long
as they don't have a real key. Random numbers are not suited for that but you
could make tempKey an object and then say
this.tempKey = new Object();
which should guarantee that every new entity is unique.
