> Handling reset() for certain fields in dyna forms would help with the 
> requirements of the <html:checkbox> tag.
> There are two approaches I've thought of so far.
> 1) Simply reset any boolean fields to false inside reset().  This could cause 
> backward-compatibility issues if anyone out there is using boolean fields in 
> action forms for anything other than checkboxes.
> 2) Allow the user to configure both an initial value and a reset flag.  This 
> could be something like:
> <form-bean 
>     name="MyForm" 
>     type="org.apache.struts.action.DynaActionForm">
>     <form-property 
>         name="firstName" 
>         type="java.lang.String" />
>     <form-property 
>         name="lastName" 
>         type="java.lang.String" />
>     <form-property 
>         name="someFlag" 
>         type="java.lang.String" 
>         initial="false"
>         reset="true"/>
> </form-bean>
> Inside reset(), any property whose "reset" flag is set would be reset to its 
> initial value.
> This would require both a DTD change, and a way for the DynaActionForm to know 
> what form name it is configured for.  For this, FormBeanConfig's 
> createActionForm() can be modified to pass along the name onto the 
> DynaActionForm it creates.
