p:菜单项onclick更新不起作用

我正在研究JSF/PrimeFaces，但当我使用来自PrimeFace的菜单项时，我的表面板不会自动工作。

<p:menuitem value="Hide Group" icon="ui-icon-close" styleClass="delete-group" onclick="pw_confirm_apply_end_date.show();return false" update="pnl_tbl_addr_group_mst" />
<p:confirmDialog widgetVar="pw_confirm_apply_end_date" message="Do you want to continue with applying end date?" style="width:300px">
  <p:commandButton id="btn_update_dlg" value="Apply End Date" icon="ui-icon-clock" process="@this" update=":form1:pnl_tbl_addr_group_mst,growl1" oncomplete="pw_confirm_apply_end_date.hide()" actionListener="#{addmst_grid.hideGroup}" />
  <p:commandButton value="Cancel" icon="ui-icon-close" onclick="pw_confirm_apply_end_date.hide();return false;" />
</p:confirmDialog>

当用户点击"隐藏组"按钮时，它会显示符合框，在他们按下"应用"后，组可以隐藏，但面板更新不起作用。

public void hideGroup(ActionEvent event) {
    FcadAddrGrpMst ent_AddrGrpMst = fcadAddrGrpMstFacade.find(selectedGroupMst.getAgmUniqueSrno());
    FacesContext context = FacesContext.getCurrentInstance();
    try {
        ent_AddrGrpMst.setEndDate(new Date());
        ent_AddrGrpMst.setUpdateby(new FhrdEmpmst(globalData.getUser_id()));
        fcadAddrGrpMstFacade.edit(ent_AddrGrpMst);
        try {
            setTbl_addr_group_mst();
            context.addMessage(null, new FacesMessage(FacesMessage.SEVERITY_INFO, "Hide Group", "Hide Group successfully"));
        } catch (Exception e) {
            logGenerator.generateLog(system_Properties.getSystemName(), Level.SEVERE, this.getClass().getName(), "hideGroup", null, e);
            context.addMessage(null, new FacesMessage(FacesMessage.SEVERITY_WARN, "Error in resetting components", "Hide Group successfully but error in resetting component(s) please refresh the page to view the changes"));
        }
    } catch (Exception e) {
        logGenerator.generateLog(system_Properties.getSystemName(), Level.SEVERE, this.getClass().getName(), "hideGroup", null, e);
        context.addMessage(null, new FacesMessage(FacesMessage.SEVERITY_ERROR, "Error", "Some unexpected error occurred while saving record(s)"));
    }
}
