$expand broke in version 0.7 with JPAProducer #219

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago
What steps will reproduce the problem?
Case 1: Use single level $expand to any relationship
Case 2: Use $expand consisting of multiple levels.

What is the expected output? What do you see instead?
Instead of returning results containing the expanded entities, the service 
returns instead:
Case 1: Uninitialized entities (example, when relationship is 1->1 or *->1) or 
no results.
Case 2: Error.

What version of the product are you using? On what operating system?
odata4j 0.7 run on tomcat on windows 7 and linux

I include my own fix of the issue. My changes are marked with comments

The fix only works for URLs not specifying entity key such as 

http://myhost.com/myService.svc/Registration(1234)&expand=student

It works only for general searches:

http://myhost.com/myService.svc/Registration&expand=student

I have developed a full solution along with other fixes for version 0.7 (enums, 
embedded types etc), but i will do it the proper way as soon as i have some 
time, ie cloning the source, fixing and and issuing a pull request.
