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>
