[T5] StreamResponse causes java.lang.IllegalStateException

[Donyee <xy...@gmail.com>]

when i click to submit the form, i got java.lang.IllegalStateException.
I search the web and found that wes because the wrong use of
response.getOutputStream(); and response.getWriter();
Is this a bug?
how to fix this?

In my java code:
StreamResponse onSuccess() {

        return new TextStreamResponse("text/json", "{key:'"+test+"'}");
    }
In my page .tml:
 <t:form t:id="testForm">
            <table>
                <tr>
                    <td>
                        test
                    </td>
                    <td>
                        <t:textField t:id="test" value="test">
                        </t:textField>
                    </td>
                    <td>
                        <a href="#" onclick="processForm();">submit</a>
                    </td>
                </tr>
            </table>
        </t:form>
<script>
var processForm = function(){
                alert('click');
                ele = jQuery('#testForm');
                var options = {
                    dataType: 'json',
                    success: function(data){
                        alert(data.key);
                    }
                };
                ele.ajaxSubmit(options);

            };
</script>
