Hi guys,

I try to lern jcouchdb at the momemt. But I have some problems updating
documents with attachments.
That code does not work as I expected:


    FooDocument document = new FooDocument( "foo with attachment" );
    document.setId( "daId" );
    document.addAttachment( "greeting", new Attachment(
MediaType.TEXT_PLAIN, "Hello World!".getBytes() ) );

    db.createDocument( document );
    assertEquals( "daId", document.getId() );
    assertEquals( "Hello World!", new String( db.getAttachment( "daId",
"greeting" ) ) );

    db.updateDocument( document );

    {
      FooDocument read = db.getDocument( FooDocument.class, "daId" );
      Attachment attachment = read.getAttachments().get( "greeting" );
      assertEquals( "2", attachment.getRevPos() );
      assertTrue( attachment.isStub() );

      db.updateDocument( read ); //This one fails with 412
    }


Basically it seems to be related to the fact, that I *read* a document
with attachments and the put it again.



Thanks,

Johannes
