JESS: Jess reported an error in routine Jesp.parsePattern Error

[Juan Sequeda]

Hi everybody

I have everything working in Jess. I define the deftemplates with slots:

(deftemplate Rel (slot name) (slot bRel))

Now I am to embed jess in my java application. I was following the Price
example, and created a model: a class for each of the templates and then
replace it in my rules file:

(deftemplate Rel (declare (from-class Rel)))

The java class has the exact slot names as I had before. However, the second
slot, bRel, is not read.

if I replace it back to the original deftemplate with slots, it does work.
Any pointers?

Thanks
