[jira] Commented: (BEEHIVE-295) change button tag to prevent RuntimeException

["Jeremiah Johnson (JIRA)" <be...@incubator.apache.org>]

     [ http://issues.apache.org/jira/browse/BEEHIVE-295?page=comments#action_59164 ]
     
Jeremiah Johnson commented on BEEHIVE-295:
------------------------------------------

My example of the correct implementation was unnecessarily long.  I should have used this in the example of what works:

--- a valid controller entry behind cancel
      @Jpf.SimpleAction( name="cancel", returnAction="newProductCancel",
         useFormBean="newProductForm" )
---

The botton line is still the same, though: I don't want my cancel to use a form bean and I don't want a Runtime Exception if I don't specify useFormBean.

> If I use a button tag in a form to cancel and the action of that button points to an action that doesn't declare a form bean, I get a RuntimeException for every field in the form.  The exceptions seem harmless, but I would rather not have the exception or have a single, specific exception.
> I will attach the stack trace that I got using the following code:
> --- in the JSP
>          <netui:button type="submit" value="submit"/>
>          <netui:button action="cancel" type="submit" value="cancel"/>
>       </netui:form></p>
> ---
> --- in the controller
>       @Jpf.SimpleAction( name="cancel", returnAction="newProductCancel" )
>    }
> ---
> The obvious work-around (and probably correct use of the cancel action in this case) work fine, so this isn't recorded as a bug against Beehive.
> --- the 'correct' controller code
> @Jpf.Action(
>    forwards={
>       @Jpf.Forward(name="success", returnAction="newProductCancel")
>    },
>    useFormBean="newProductForm"
> )
> protected Forward cancel( NewProductForm newProductForm ) {
>    return new Forward( "success" );
> }
