rec.campsiteFri() probably return a Boolean (the class), not the basic boolean data type.
Default NSKeyValueCoding implantation does the coersion for free.

I used eomodeler to generate the model and EO classes from a Postgresql db.
I'm having a problem using the boolean data type. If I reference a boolean
field 'rec.campsiteFri()' like so:


if (rec.campsiteFri()) {
            return true;
        }

I get a compiler error 'incompatible types'. I can't use the field in
WOBuilder as it throws a java class cast exception.

I've read previous posts saying there are problems using boolean types in
eomodeler. Should I be avoiding booleans altogether in my db design and use
integer instead?



Here's the eomodeler specs for this field:

ext type    val class (java)    val type    val class   prec
-------     ----------------    --------    ---------   -----
bool        Number              c           NSNumber    1
