Hi,

you might want to try to replace "loanToValue()" with "loanToValue" and
report whether it works. I'm not sure whether the () are actually in
your rules code or a copy/paste error, but if they are, it'll be worth a
try.

This would at least somehow match the error message you reported. When
using the java dialect, you can simply use property names inside the
constraints sections. No need to add parentheses.

Kind regards
