hi
for me your code seems ok. as far as i know it should be equal
to have a <property ..> for the loop-var and to have an abstract
getter/setter in your page-class. but i remember that i also
had such problems - can you try to add to your page-class
(and maybe remove the property)
public abstract QuotationProduct getCurrentQuotationProduct();
public abstract void setCurrentQuotationProduct( QuotationProduct qp );
