commitChanges() doesn't imply commit in db ?
---------------------------------------------
Key: CAY-790
URL: https://issues.apache.org/cayenne/browse/CAY-790
Project: Cayenne
Issue Type: Bug
Components: CayenneModeler GUI
Environment: Winxp, Eclipse SDK Version: 3.2.2 Build id:
M20070212-1330, Cayenne, Version: 2.0.2 (January 14 2007),
Reporter: K. Wood
Assigned To: Andrus Adamchik
Priority: Blocker
have been reading the mail archives and didn't see where this problem ever got
fixed.
I am have the exact same thing going on with HSQLDB.
I have the latest versions of that and Cayenne, etc.
Everythign looks hunkey dorey no runtime errors & such, until you access the db
with Squirrel SQL. Nothing is there at all!! No commits.
This is just the little demo program with the artists and paintings I'm sure
you've seen a zillion times. ( got too many imports, for testing things atm.)
Nothing I have tried works at all.
I even tried with Derby..which I haven't been able to get to work without
compiler errors as yet.,
(the Cayenne GUI Modeler creates the empty db but this same code wont compile)
anyway...
After reading all the other mail, I think there is a widespread problem here.
Hope you can shed some light on this.
See what you think:
Code:

public class up_dt {
public static void main(String[] args) {
DataContext ctxt = DataContext.createDataContext();
Artist picasso = (Artist) ctxt.newObject(Artist.class);
picasso.setName("Pablo Picasso");
picasso.setDateOfBirthString("18811025");
Gallery metropolitan = (Gallery) ctxt.newObject(Gallery.class);
metropolitan.setName("Metropolitan Museum of Art");
Painting selfPortrait = (Painting)
ctxt.createAndRegisterNewObject(Painting.class);
selfPortrait.setName("Self-portrait");
selfPortrait.setYear(new Integer(1907));
selfPortrait.setArtist(picasso);
metropolitan.addToPaintings(selfPortrait);
Painting theDream = (Painting)
ctxt.createAndRegisterNewObject(Painting.class);
theDream.setName("The Dream");
theDream.setYear(new Integer(1932));
theDream.setArtist(picasso);
metropolitan.addToPaintings(theDream);
// Set artist on both paintings; as a side effect this will
automatically
// add these paintings to the Artist's paintings collection.
// theDream.setArtist(picasso);
// Painting girl = (Painting) ctxt.newObject(Painting.class);
// girl.setName("Girl Reading at a Table");
// Painting stein = (Painting) ctxt.newObject(Painting.class);
// stein.setName("Gertrude Stein");
// picasso.addToPaintings(girl);
// picasso.addToPaintings(stein);
// girl.setGallery(metropolitan);
// stein.setGallery(metropolitan);
ctxt.commitChangesToParent(); // not committing the updates.
Why?
//
}
