Michael Neale commented on JBRULES-261:
---------------------------------------

defaintely automatic. We don't want to be as rigid with types as java is.

Of course, if there is any "loss" of data resolution, that is a problem, but if there is not, then automatic is good.

> Problem: If a rule compares two fields and one of them is a char and the
> other one is a String, the match is always negative. No type-mismatch error
> or warning is displayed. This can be quite confusing. The attached Eclipse
> project illustrates this problem.
> Suggested Solution: If all information is available at compile-time an error
> should be generated on type mismatches. Otherwise there should be a warning
> during run-time and maybe a type conversion attempt.
