<form:select problem

guys

i have a problem with <form:select tag. I have a <form:select tag for which the options are supplied through a dynamic collection from the request scope. When i submit the form and if the validation fails, the value i chose when i submit the form gets reset and it always shows the first option in the drop down..

but if i supply the values with each <form: option tag statically, it retains. the issue is only if the values are supplied dynamically which is what i need as well..

any clue ...whats going on?

Are you using automatic validation? If you are, then I don't think you have to do anything special...your "formView" should have the form available -- unless it is doing a redirect (though I can't see a reason why someone would do that, but it is possible).

Code:

---

<property name="formView" value="mybodyT" />
or
<property name="formView" value="redirect:/s/something.html" />

---

In our controllers when we're NOT using automatic validation, we generally do something like

Code:

---

        getValidator().validate(form, errors);
        if (errors.hasErrors()) {
            return showForm(request, response, errors, errors.getModel());
        }

---

Thoug I might add that our HTML elements (like select lists, etc) have their data created by the referenceData() method and showForm eventually calls referenceData(). (high level Live cycle visio/jpeg available upon request)

BaseCommandController's setValidateOnBinding() The default is true, I believe.
