Hi
Sounds as if there went something terribly wrong with your generation. Have you
checked NewGenerateMapBuilderTask.txt for usage specifications.
I suspect you only copied the ant description without setting the variables to
appropriate values. From the txt file:
<quote>
To let the generated MapBuilder files extend a superclass
specify the "extend" property. If you leave this property
blank the generated classes will import the MapBuilder
interface and provide the required implementations. If
you do specify an "extend" class you should provide
implementations of the MapBuilder methods in your
superclass. You will also need to add the following
member variable to the superclass:
protected DatabaseMap dbMap = null;
</quote>
If you've done all this and you still have problems, please let me know for that
will mean there is a bug somewhere in the code that needs fixing.
I'll also send a correct class to you by private e-mail so that you can at least
have a working example. This is one of the classes I use in my own projects and
it is in it's original unmodified generated state :-)
