I've created an Entity Bean (CMP) that loads data from a table containing some columns. One of these column is of type BigDecimal and can be NULL.
The problem is when I try to call a business method ( getXXX( ) ) on this bean. It throws an exception ( java.lang.IllegalArgumentException ) that occurs in $Proxy42.getXXX( ). But when I set a value to the column mapped to that method, then I can successfuly call all getXXX() methods on the bean.
