Adding data to model when using showForm()

[slnm]

I have a view which I use for several submit actions. Each action should return the same view (ie, I delete an item from a list and onSubmit gives me the same view with the same command state).

To achieve this, my onSubmit method returns showForm() as a ModelAndView to "redisplay the form". However, I want to give the user a message if an action went fine or if it didn't (ie - Error deleting an item) but I'm having trouble adding anything to the model that the showForm returns.

Oh dear, I'm slow today. Of course you can return a model with showForm (request, response, errors, model)

Could you please tell me how to do this as I'm stuck

[slnm]

Sure.

In your onSubmit method, if you want to redisplay the form, instead of returning a new ModelAndView, create a new Map ie

Map<String, Object> model = new HashMap<String, Object>();
model.put("someData", "something");

and return

return showForm(request, response, errors, model);

Then in the JSP you can simply get the model data the way you normally would, by calling ie

<c:out value="${someData}"/>
