    ----------------------------------

    Yes, it will be done, but the best way forward isn't 100% clear yet. See this for discussion:

    > I realize that this would restrict functionality to Java 5+, but I still believe it would be a good option to have for the code generator in the modeler:
    > Add, as an option, generic types to Lists in generated classes. It's quite annoying to have to cast types; much of my code looks like this:
    > for(Object o : someObject.getSomeManyToManyField()) {
    > TheTypeIWanted ttiw = (TheTypeIWanted) o;
    > ...
    > }
    > With generics, it would be:
    > for(TheTypeIWanted ttiw : someObject.getSomeManyToManyField()) {
    > ...
    > }
    > It'd also be nice if the core libraries had generics. For example, "Object DataObjectUtils.objectForPk(Class, int)" could be changed to "T DataObjectUtils.objectForPk(Class<T>, int)" to avoid casting.
