trying to persist byte[] field fails

[ms]

hi,

i am new to orientdb and have run some successful tests.
what i am trying to achieve is to persist classes that were generated
by jaxb2.
persisting jaxb2 generated classes seem to work well unless they
contain fields of the following kind:

protected byte[] uniqueid;

saving a class that contains such a field results in the following
exception:

java.lang.IllegalArgumentException: Type LINK must be a collection

Hi,

the reason is a old bug on auto-discovery of type when you're working in schema-less mode. To fix:

- create a schema for that class with a property of type "binary"

- checkout latest SVN trunk

What version are you using?

bye,

Lvc@

[ms]

i used latest svn trunk (1703)

for test purposes i modified the InheritanceTest's create() method and
ran InheritanceTest only:

@Test
public void create() {

database.open( "admin", "admin" );

OClass account = database.getMetadata().getSchema()
.createClass( "Account",
database.getStorage().addCluster( "account",
OStorage.CLUSTER_TYPE.PHYSICAL ) );

OClass c =
database.getMetadata().getSchema().createClass( "Company" ).setSuperClass( account );
c.createProperty( "ucpTuniqueId", OType.BINARY );

OClass profile = database.getMetadata().getSchema()
.createClass( "Profile",
database.getStorage().addCluster( "profile",
OStorage.CLUSTER_TYPE.PHYSICAL ) );

startRecordNumber = database.countClusterElements("Company");

Company company;

for (long i = startRecordNumber; i < startRecordNumber +
TOT_RECORDS; ++i) {
company = new Company( (int) i, "Microsoft" + i );
company.setEmployees( (int) (100000 + i) );
company.getAddresses().add( new Address( "Headquarter", redmond,
"WA 98073-9717" ) );
company.setUCPTuniqueId( new byte[] { 0x03, 0x00, 00, 0x1A, 0x7B,
0x62 } );
database.save( company );
}

database.close();
}


and received:

FAILED: create
java.lang.IllegalArgumentException: Type BINARY must be a collection

Hi,

the problem was of Object Database wrapper. Can you try now with last SVN?
