I am moving a Struts-based application from WebLogic 5.1 to 6.1 and I am
encountering some strange errors. Has anyone else seen this behavior before,
or know what might be causing it? I have a Collection of beans I am trying
to iterate through using the Struts iterate tag (works fine with WL5.1) but
now I am getting an error that there is no getter method. I have verified
with the debugger that at runtime the Collection exists and it is populated
with the expected objects. I am not really sure what is going on... The only
thing I can think of is that this method does not exactly conform to the
JavaBean spec- it does not set/get the same type of object. When doing a
set, you pass it a TimeStamp but for the get it returns a formatted String
(see below). However, the naming conventions are followed correctly. Is this
a problem?

note: the bean called "theFermentation" is a FermSummaryBean (see below)
