我正在使用primefaces-3.4并且有一个对话框(详细信息页面),以显示母版页上数据表中所选项目的详细信息。我的bean是@ViewScoped,在actionListener方法我正在加载详细信息。显示母版页时,首先单击p:commandButton,它不会填充对话框,在第二次单击时它会正确显示。我已经使用Chrome开发人员工具进行了检查,并且没有看到任何异常,只是所选项目的详细信息没有“绑定”到UI。
这是我的bean代码和xhtml
@PostConstruct
public void init() {
// load credits if there is an account selected...
if (mainBean.getSelectedAccount() != null) {
ArrayList<Credit> cs = loadCredits(mainBean.getSelectedAccount());
setCredits(cs);
mainBean.getSelectedAccount().setCredits(cs);
}
if (this.selectedCredit != null) {
ArrayList<Installation> installations = loadInstallations(selectedCredit);
selectedCredit.setInstallations(installations);
setPaymentAmount(Float.parseFloat(installations.get(installations.size()-1).getAmount()));
}
}
....
//actionListener to select
public String select() {
if (selectedCredit != null) {
ArrayList<Installation> installations = loadInstallations(selectedCredit);
selectedCredit.setInstallations(installations);
}
return null;
}
这是我的xhtml中的片段

那么究竟是什么问题?
答案 0 :(得分:0)
AFAIK,actionListener方法必须具有签名:public void actionListener(ActionEvent event)
。您可以尝试使用action
代替actionListener
。
另外,您是否有数据表的封闭表格?使用多个表单时,JSF中存在一些错误。尝试更新整个表单而不是仅对话:update=":productdetailform"
