After I made all the classes part of a package, everything was
fine, apart from the fact that they were 5.4-ish, and I want 5.3.
So I went to the second EOGenerator solution,
You can use JavaEOGenerator to produce 5.3 classes -- you just need
to modify the templates to not use 5.4 features.
I tried that, but there are some strange things: if there is no
class definition, eg it is just EOGenericRecord, it will create a
class EOGenericRecord, and _EOGenericRecord, or
com.webobjects.eocontrol.EOGenericRecord, depending on how the
thing is defined in the EOModel.
I don't ever use EOGenericRecord classes, but I thought that if you
wanted this, that you should leave the class names blank in the
entity definition.
Also, it seems that there are some strange things going on with
n:m relations.
For instance, I have an n:m relation between product and review,
so there is a connection table reviewproduct, with a class
RevIewProduct.
Now I get an error in Product in this statement:
EOQualifier inverseQualifier = new
EOKeyValueQualifier(nl.immix.ReviewProduct.PRODUCT_KEY,
EOQualifier.QualifierOperatorEqual, this);
with the error:
nl.immix.ReviewProduct.PRODUCT_KEY cannot be resolved
which i scompletely logical as there is nno PRODUCT_KEY in the
ReviewProduct class.
Not sure I follow ... If you are expecting to be able to access
ReviewProduct.product(), you will need to make a class relationship
named "product" on your join class. You can't qualify on a non-
class relationship. If it was a class relationship, then the
templates would produce a PRODUCT_KEY for you.
Sorry for the confusion:
Perhaps some pictures and source code will make it clearer (I hope)
The model has a n:m relation from review to product, so I'd there is
a table reviewproduct that only contains the id's of a review and
the id of a product. that translates in EOModeler to such a
construction:
<pastedGraphic.png>
With Review Product being just a table in between.

The source code of _ReviewProduct, however does not define
PRODUCT_KEY, nor REVIEW_KEY:
