[Ur] Joining Nullable to Non-nullable fields

Hey everybody,

Something that's been bothering me for some time now. Is it possible to
OUTER JOIN a nullable field to a non-nullable field? I keep getting type
errors and can't figure out how to tell the compiler he should only do the
join for the records that the nullable field is non-null... SQL surely
allows this, but I haven't figured it out in Ur/Web yet.

Any help much appreciated!

Keep up the good work.

Simon
