Hello guys.
Well, finally after "solving" ( i dunno yet if its gonna worl the
solution or what) the problem with the "execute SQL" Im going
trough the tutorial, IO read I should use the Veogen due that im
under leopard. so I did what the wiki says
http://wiki.objectstyle.org/confluence/display/WOL/Velocity+EOGenerator+(Veogen)
no problem there.
so comparing the sample code I downloaded from the site where the
tutorial resides and with the code generated (DisplayBoard.java and
_DisplayBoard.java) there are some diferences, i.e the constructor
its missing, I don't have any issue in putting just super();, but
Im wondering if I will have some p[roblems in the future...
Veogen templates do the right thing. Don't worry about the missing
constructor, do not added it, you will (and should) never call it
directly.
When creating a new DisplayBoard you'll see in the code for the
tutorial that Janine uses:
DisplayBoard displayBoard =
(DisplayBoard)EOUtilities.createAndInsertInstance(session
().defaultEditingContext(), "DisplayBoard");
This is such a common line of code that the Veogen templates
generate factories that do that for you.
So you can call:
DisplayBoard displayBoard =
DisplayBoard.newDisplayBoard(session().defaultEditingContext());
I guess I should have put in a reference to the canonical EOF
