Anthem Bug:当页面同时出现Anthem.FileUpload和TextArea时callback出错(BADRESPONSE)

出错情况

1. 页面放Anthem.FileUpload,TextArea(Anthem.TextBox),Anthem.Button.用户先选择了一个文件(没有选择文件不存在后面的问题),然后再点击Button时,在点击事件里改变TextArea的Text值并设置UpdateAfterCallBack为true.callback失败,提示BADRESPONSE.

            前台:
               <anthem:FileUpload ID="FileUpload1" runat="server" />
               <anthem:TextBox ID="TextBox1" runat="server" Height="56px" TextMode="MultiLine" Width="246px"></anthem:TextBox>
               <anthem:Button ID="Button1" runat="server" OnClick="Button1_Click" Text="Anthem Upload Button" />
            后台:
               protected void Button1_Click(object sender, EventArgs e)
               {
                       TextBox1.Text = "afdasdfas";
                       TextBox1.UpdateAfterCallBack = true;
               }

目前针对以上两种情况,我的解决办法是添加Button的PreCallBackFunction="ResetForms"(红色部分)

function  ResetForms()
     {
        var fileUpload = document.getElementById("<%=PhotoFileUpload.ClientID %>");
        if(fileUpload!=null && fileUpload.value!="")
        {
            document.forms[0].reset();
        }
    }

其实就是刷新form.不知道还有没有更好的解决办法.
