        @Override
        public byte[] getData(Attributes attributes) {
            return control.getExportPreviewByteStream(estimateModel.getObject());
        }
    }) {
        private static final long serialVersionUID = 1L;

        @Override
        protected String getTriggerJavaScript() {
            String js = super.getTriggerJavaScript();
            js = "document.getElementById('" + form.getMarkupId() + "').target='_blank';" + js; …
