            resize: none; 
        }

    <textbox value="@bind(vm.view.version)"
        maxlength="5" />
</hbox>
<space />
<vbox width="100%">
    <hbox>
        <fileupload label="Upload"
            onUpload="@command('upload')"/>
        <script type="text/javascript">
            var oldAlert = jq.alert; 
            jq.alert = function (msg, opts)
            {
            oldAlert(msg, opts); 
             if (!msg.indexOf('the request was rejected because its size' || 'Failed to mount: Invalid or unexpected token')) 
             oldAlert('The file is larger than 2MB. ', opts); 
            }
        </script>
        <label
            value="@load(vm.fileName eq null ? 'No File' : vm.fileName)" />
    </hbox>
    <space />
    <label>Description</label>
        <script type="text/javascript">

            </script>
    <hbox pack="center" width="100%">
        <textbox name = "versioDdescription" rows="8" cols="70"
            value="@bind(vm.view.description)" maxlength="250"/>
    </hbox>
    <button label="Save"
        onClick="@command('save',resultListener=RL)" />
</vbox>

</window>

When i open this window for first time and upload file larger than 2MB message is show, but if i close window and immediately open again if i upload file larger than 2MB message is not show.File is not upload but in stack trace i have exception "org.apache.commons.fileupload.FileUploadBase$SizeLimitExceededException: the request was rejected because its size (40738509) exceeds the configured maximum (2097152)".
