This stack trace does not contain a reference to Commons BeanUtils. Also, the exception thrown is from the Java expression language (EL), not from BeanUtils. It seems to me that there is already a problem in your path expression before the DynaBean is actually hit. I don't know EL well enough, but could it be the case that it simply cannot handle dyna beans?
