Ext.QuickTips.register({ target: ComboRegisted.combo.getEl(), text: COREProxy.languageMng.getText(oThis.CLASS_NAME, "tooltipNormativaFechaAprobacion") + raw.fechaAprobacion + 
"<br/>" + COREProxy.languageMng.getText(oThis.CLASS_NAME, "tooltipNormativaCO") + raw.normaCO + COREProxy.languageMng.getText(oThis.CLASS_NAME, "tooltipNormativaUnidad1") +

没问题，我现在得到答案了。
