QUESTION
I would like to use JaVers to track changes of my Java objects. The basic examples are working fine, but I can't get it to detect changes on objects stored in a collection.
If I extend the ChangeLogExample.class example to change e.g. one of the sub-ordinates:
...ANSWER
Answered 2017-Jun-08 at 13:48Ok, a few issues here.
First of all, Empolyee
objects are mapped as Entities
. So in JaVers, there is no
parent/child relationship between them (in fact any kind of relationship).
That's why withChildValueObjects()
filter doesn't apply here.
It works only for ValueObjects
owned by Entities
, see http://javers.org/documentation/jql-examples/#child-value-objects-filter
Still, there are two ways to improve your query.
Ask directly for the Entity instance you want to trace.
Use the new Shadow API with Query Scopes, see http://javers.org/documentation/jql-examples/#query-for-shadows It's a new feature and will be improved in the feature. You can use it already if snapshots of both Entities will be selected by the query.

Install repository-examples
PHP requires the Visual C runtime (CRT). The Microsoft Visual C++ Redistributable for Visual Studio 2019 is suitable for all these PHP versions, see visualstudio.microsoft.com. You MUST download the x86 CRT for PHP x86 builds and the x64 CRT for PHP x64 builds. The CRT installer supports the /quiet and /norestart command-line switches, so you can also script it.
