JPAProducer: enums not suported #133

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. create an entity with an enumfield and @Enumerated(EnumType.STRING)

What is the expected output? What do you see instead?
Trying to read this filed will result in an ClassCastException in OProperties 
in line 72 when attempting to cast the enum to String.
I would like the value instead of an Exception.

a solution would be to invoke the toString() method of the value instead of 
casting.

What version of the product are you using? On what operating system?
Using Version 0.5, OS: Windows XP SP 3

Please provide any additional information below.

A patch for version 0.6: Goto org.odata4j.core.OSimpleObjects.java line 27 and 
replace the 'if' statement with a single line: 

sValue = value.toString();

The fix works for version 0.7 too. I attach the OSimpleObjects.java file for 
version 0.7 for your convenience.

Bear in mind that, as exposed by the service's metadata even without the fix, 
enums are represented as strings. I also warn you that I have only tested 
reading such entities holding enums, not creating nor editing, and the fix only 
pertains to reading. I don't know whether this is enough for creating or 
editing.

I think that the 'if' wasn't needed to begin with.
Since toString() belongs to the Object class there isn't much point in casting 
into a String object.

Has this fix implemented and included in 0.7.0 ?

It is fixed in the following pull request:

https://github.com/odata4j/odata4j/pull/3

It supports both reading and writing enum fields.
