Wrapping an ODocument causes fields not to be saved

[Alberto Siena]

Hi

After struggling a  lot I found that wrapping an ODocument into another class causes fields not to be saved as I expected. Consider for example the two functions and the DummyRecord class reported below; to me they seem to do the same thing, but the output is different:

> select from Source

---+---------+--------------------

  #| RID     |links               

---+---------+--------------------

  0|    #21:4|{linkName:[1]}      

  1|    #21:5|null                

---+---------+--------------------

So what's wrong with wrapping an ODocument like DummyRecord does? Is there any caching issues I should consider? (I'm using rc9)

Thanks

Alberto

public void test1() throws Exception

{

DummyRecord target = new DummyRecord( "Target" );

target.save();

DummyRecord source = new DummyRecord( "Source" );

target.save();

ODocument out = source.getODocument().field( "links", OType.EMBEDDED );

if( out == null )

{

source.getODocument().field( "links", new ODocument(), OType.EMBEDDED );

}

out = source.getODocument().field( "links" );

List<ODocument> links = out.field( "linkName", OType.EMBEDDED );

if( links == null )

{

links = new ArrayList<ODocument>();

out.field( "linkName", links, OType.LINKLIST );

}

links.add( target.getODocument() );

source.save();

}

public void test2() throws Exception

{

ODocument target = new ODocument( "Target" );

ODocument source = new ODocument( "Source" );

ODocument out = source.field( "links", OType.EMBEDDED );

if( out == null )

{

source.field( "links", new ODocument(), OType.EMBEDDED );

}

out = source.field( "links" );

List<ODocument> links = out.field( "linkName", OType.EMBEDDED );

if( links == null )

{

links = new ArrayList<ODocument>();

out.field( "linkName", links, OType.LINKLIST );

}

links.add( target );

source.save();

}

public class DummyRecord

{

ODocument doc;

public DummyRecord( String cname ){

doc = new ODocument( cname );

doc.field( "links", new ODocument(), OType.EMBEDDED );

doc.save();

}

public ODocument getODocument(){

return this.doc;

}

public void save() {

this.doc.save();

}

}

For those who may be interested: removing the doc.save(); in the DummyRecord constructor makes it work.

Now my question is: why???

Hi Alberto,

don't know why the first save makes a mess. Could you open an issue for that?

Sure
