  • Re: Dudad sobre Object_Manger

    Catman, igual es compleja la consulta que quieres hacer... ya que si suponemos que es lenguaje SQL o similar,funcionaria para una BD relacional, en la cual no existe un atributo multiobjeto, sino un FK que referencia a una tabla intermedia que une el empleado con FK a la tabla de titulos.. por lo cual la consulta seria igual compleja mediante sql ...

  • Re: ObjectManager throws NullPointerException

    I'm having this problem as well and closing the database doesn't seem to solve it. Even if I create an empty database (with .Net) I can't seem to open it. Any ideas?

  • Use of Object Manager to add/update/delete objects

    Hello,  I am trying to use the object manager in conjunction with DB4Objects. I was wondering if there is a facility to add new data objects to the database using object manager. I was able to query the database but I could not find a way to add new objects to the database. So please let me know if that can be done using object manager.

    IObjectContainer.Close() should be fine. If there are pending commits, it will call commit().

  • Re: ObjectManager 6.4 is not working on my home PC

    I experience this from time to time. Actually, I had an earlier posted problem with the object manager 6.4 problem but eventually, it ended that it was my mistake. Try checking on the following: (1) Java Runtime Version (it should be latest) (2) In CS mode, check the way you open the database using OpenServer or if it is really open up and ...
