Extend form-bean in struts-config
Hi
In my struts config, I have a few forms, with type DynaValidatorForm. The problem is, I have a few forms who share a few fields. Is there a way to declare a superform and let the other extend that form, so that I don't have to declare the common fields for every form?

Oh, I didn't know you meant as a Tiles controller.
Still, I don't know why not.

The "....so on" part is probably helpful.

So would this be a valid definition?
<definition name="VitalSigns.Input"
path ="/tiles/VitalsMainInput.jsp"
controllerUrl= "/VitalSigns.do?action=edit" >
</definition>
where edit is method in VitalSignsAction and action is the parameter in my action mapping. It doesn't seem to work for me. I get this error:
'/tiles/VitalsMainInput.jsp': ServletException in '/tiles/VitalsMainInput.jsp': Servlet execution threw an exception

Does anyone know if these two can somehow be used together?

Yes, using the 'extends' attribute. Something like:
<form-beans>
<form-bean name="base" type="...DynaValidatorForm">
<form-property name="value1"/>
<form-property name="value2"/>
...
</form-bean>
<form-bean name="form1" extends="base">
...
</form-bean>
</form-bean>
Note, this is a relatively recent feature in Struts 1, so you may need
to upgrade to take advantage of it (I believe it was introduced in the
1.3 series).
