> 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.
