In my experience this works fine.

What is the best way to set a date field as a hidden property?
Will is just work if I use <html:hidden and a date property?

Hi Nathan,
I had this (or a similar) problem when I tried to populate a date field. It seems that a null or empty String is not a valid value for conversion to a Date. I remember the issue having something to do with BeanUtils' converter not having a default value for Date. Any chance this is the case?

When I copy a DynaActionForm to my class. Strange thing is that I just did the reverse and it worked.
Code that works ...
Report report = (Report) tree.findNode(node); DynaActionForm dForm = (DynaActionForm)form; BeanUtils.copyProperties(dForm, report);
Code that breaks ...
DynaActionForm dForm = (DynaActionForm) form; Report report = new Report(); BeanUtils.copyProperties(report, dForm);
Here is the form bean ...
<form-bean name="reportForm" type="org.apache.struts.action.DynaActionForm">
<form-property name="name" type="java.lang.String"/>
<form-property name="id" type="java.lang.String"/>
<form-property name="description" type="java.lang.String"/>
<form-property name="archive" type="java.lang.Boolean" initial="false"/>
<form-property name="brioJobId" type="java.lang.String"/>
<form-property name="type" type="java.lang.String"/>
<form-property name="postedDate" type="java.lang.String"/>
<form-property name="frequency" type="java.lang.String"/>
</form-bean>
