got some pain in this process ..
in FilterToSQL
public Object visit(Literal expression, Object context) throws
RuntimeException {
LOGGER.finer("exporting LiteralExpression");
//type to convert the literal to
Class target = (Class)context;
//JD except for numerics, let the database do the
converstion
Object literal = null;
line 747: if ( Number.class.isAssignableFrom( target ) ) {
blows up, because...
on line 177, same file, but a few calls back in the trace:
filter.accept(this, null);
is called. Which always seems to blow up with the null pointer
What am i missing,
PS - is there a lucidd explanation anywhere of the extraData parameters....
