Hi,
There is a problem when I try to use an OQLQuery that mixes tables that have
the column ojbConcreteClass and tables that don't have it.
If I extends different classes from resources and only to classes are stored
in the same table and there is another class that is stored in his own table
I get the error (Attribute "ojbconcreteclass" not found).
The query might be:
query.create("select all from "+Resource.getName());
If you do a Query with a class that involves classes on the same table there
is no problem.
If you do a Query with a class that involves classes that are stored each on
his own table there is no problem.
How can I overcome that? Is it really a bug? I am missing something?
Thank you.
Mauricio CASTRO.
