Description bennyv 2009-06-29 09:31:02 UTC
Whenever I generate entity classes from an existing database that contains multi column primary keys, no default 
constructor is generated for them. The editor also indicates/warns that the default constructor is missing.

I have tested this against Netbeans 6.5 which does generate a default constructor.
I have run the same test with Netbeans RC6.7 RC3 in which the default constructor for a PK-class representing a multi 
column PK is not generated.

I am running Netbeans on 32 bits Windows Vista. The database with which I am testing is Oracle 11g.
Comment 1 Sergey Petrov 2009-07-01 10:04:07 UTC
can you attach schema for your database?
Comment 2 Sergey Petrov 2009-07-01 10:22:20 UTC
or can you try the same with sample database or generated from db schema(if schema is correct) to find out if it's
oracle specific, I tried to create table with two columnt pk in sample and got correct pk class with default no arg
it may also be a good luck to have it working in 6.5 as oracle 11g isn't listed as tested platform for 6.7 on  and this way can't be considered as
fully supported.
Comment 3 Sergey Petrov 2009-07-01 10:32:46 UTC
About working configuration: I tried it with 6.7 release, on java 6, on linux with sample derby database.
Comment 4 bennyv 2009-07-01 11:27:55 UTC
I have tried it with NetBeans FCS this moring as well, when running the following tutorial against a derby database: I had to manually add the default constructors for PK 
classes ClientPK and ProjectPK.
I will attach a sql script for my Oracle schema as well.

Comment 6 Sergey Petrov 2009-07-01 11:36:35 UTC
ok, looks like I need to try vista, what jdk do you use?
Comment 7 Sergey Petrov 2009-07-01 11:39:13 UTC
thanks for your script.
Which tables did you use in entity classes generation? I see there are a lot..
Comment 8 bennyv 2009-07-01 11:58:33 UTC
In fact I generated entities for them all. 
I just tested it again and have to make some extra remarks:

When I tried to only generate entity class for "Huurovereenkomst" entities "Woning" and "Huurder" were selected as 
well (based on their dependencies). In this case, the default constructor IS created.

Whenever I try to generate the entities for all tables, the default constructor for all PK-classes is omitted...

used jdk: jdk1.6.0_14

Comment 12 Sergey Petrov 2009-07-16 13:34:17 UTC
was abe to reproduce with last script+derby+generate for all tables, got missing def constrctor
Comment 13 Sergey Petrov 2009-07-17 09:07:12 UTC
As I see MethodInfo is created incorrectly also it's created in nbjavac/java.source code, so pass to java-source either
to ask assistance or to find if it's a problem in nb-javac or java.source part and fix it.
Comment 14 Sergey Petrov 2009-07-17 09:41:05 UTC
a bit more details return false for these constructors, but
later when JCClassDecl is rewriten an code is generated, no code for these constructors is generated, so may be code gen
use another method to get if constructor should be in code or not.
Comment 15 Sergey Petrov 2009-07-17 13:23:59 UTC
with Dusan help find a way to fix on my side, but still want to be sure if there is any issue on javac, javac usage size
Comment 16 Sergey Petrov 2009-07-17 13:31:57 UTC
fixed in by switch from ElementUtilities to TreeUtilities.
going to investigate a bit more before closing, not closing, filing related separate issue or any more steps.
Comment 17 Quality Engineering 2009-07-20 09:49:01 UTC
Integrated into 'main-golden', will be available in build *200907200201* on (upload may still be in progress)
Log: fix #167773 - changed a way to find if constructor is "generated/synthetic"
Comment 18 David Strupl 2009-07-20 12:29:56 UTC
Sergej, can this be marked as fixed?
Comment 19 Sergey Petrov 2009-07-20 14:04:00 UTC
I'm waiting if it will be fixed in root cause by Dusan and also waiting for a response from him.
Comment 20 Sergey Petrov 2009-07-22 10:47:24 UTC
rollback my fix
issue is fixed in nb javac
Comment 21 Quality Engineering 2009-07-23 07:43:45 UTC

Comment 23 bennyv 2009-07-23 12:18:17 UTC
I have downloaded the latest development build and tried against my Oracle schema. The default constructors are 
generated by this version of the IDE. Seems ok now.
Comment 24 Michel Graciano 2009-08-25 03:23:06 UTC
User bennyv said it looks fixed. Marked as verified. Please reopen if you think it is still valid.
Comment 25 Michel Graciano 2009-08-25 19:41:15 UTC
