Displaying multiple form errors

[Shahzad Bhatti]

I am trying to build a form with multiple fields and would like to show all 
errors when form validation fails. From looking at samples, it looks like we 
can only have one Form.Flag per box pane such as following snippet from 
Forms.java

        submitButton.getButtonPressListeners().add(new ButtonPressListener() {
            @Override
            public void buttonPressed(Button button) {
                String lastName = lastNameTextInput.getText();
                String firstName = firstNameTextInput.getText();

                Form.Flag flag = null;
                if (lastName.length() == 0
                    || firstName.length() == 0) {
                    flag = new Form.Flag(MessageType.ERROR, "Name is 
required.");
                }

                Form.setFlag(nameBoxPane, flag);

                if (flag == null) {
                    errorLabel.setText(null);
                    Prompt.prompt("Pretending to submit...", window);
                } else {
                    errorLabel.setText("Some required information is missing.");
                }
            }
        });

 Is it possible to show error messages next to each field when form validation 
fails. I would appreciate for any examples. Thanks.
