p:对话框中的清除表单在操作/方法调用失败后关闭

Question

我在p:dialog通过AJAX提交的组件中有一个表单.对话框中的表单是通过ui:include另一个.xhtml只包含表单及其组件的表单(不,我不是嵌套表单;对话框本身不是任何形式).包含页面的支持bean是'ViewScoped'.

MOST的功能很好:

• 成功验证后,表单将执行save方法; 成功保存后,对话框关闭; 打开后续记录会显示数据库中的正确记录信息.
• 验证失败后,提交的值将保持不变,对话框将保持打开状态并显示验证错误,修复无效字段并在成功保存时重新提交结果.

当被action调用p:commandButton失败时,问题就出现了.如果失败,对话框保持打开状态,并向用户显示"保存更改错误" h:messages; 此外,提交的值仍然存在于输入字段中.当表单保持打开时,这很好(甚至是期望的) - 但是在关闭对话框并重新打开它时,提交的值仍然在文本字段中.这很糟糕,因为它给用户留下了保存成功的印象(h:messages由于对话框更新,组件现在是空白的).

到目前为止,我已经尝试了以下内容,其中没有一个已经解决了这个问题:

• 1.1)在打开的对话框中将包含表单的支持bean设置为bean的新实例.
• 1.2)由于bean现在是一个新实例,我还使用数据bean中的详细信息重新填充地址对象.
• 2.1)禁用对话框上的关闭按钮并添加一个p:commandButton"取消"按钮,其中包含一个p:resetInput组件以关闭对话框/重置表单.(对话框关闭,但表单中提交的值仍然存在).
• 2.2)从中调用一个方法p:commandButton,删除RequestMap包含表单的辅助bean.
• 2.3)尝试将按钮设置为immediate=true和immediate=false.
• 2.4)尝试按下设置的按钮process=@this,我用来关闭表单的类似策略,以确保它在重新打开时会有新的字段.

您可以考虑将支持bean设置为新实例,并重新填充地址对象,我会看到一个新的形式,但是NOPE.

Recorddetailsform(用于调用地址对话框的表单的辅助bean)

public void showDlgAddress(){
        FacesContext ctx = FacesContext.getCurrentInstance();
        ELResolver resolver = ctx.getApplication().getELResolver();
        RecordDetails recordDetails = (RecordDetails) resolver.getValue(ctx.getELContext(), null, "recordDetails");

        //Set addressform backing bean to new instance and load address into it from recordDetails
        resolver.setValue(ctx.getELContext(), null, "addressform", new Addressform());
        Addressform addressform = (Addressform) resolver.getValue(ctx.getELContext(), null, "addressform");
        addressform.setAddress(recordDetails.getAddress());
    }

Addressform(地址表的辅助bean)

public void save() {
    FacesContext ctx = FacesContext.getCurrentInstance();
    RequestContext rctx = RequestContext.getCurrentInstance();
    ELResolver resolver = ctx.getApplication().getELResolver();
    Records records = (Records) resolver.getValue(ctx.getELContext(), null, "records");
    RecordDetails recordDetails = (RecordDetails) resolver.getValue(ctx.getELContext(), null, "recordDetails");
    Mainform mainform = (Mainform) resolver.getValue(ctx.getELContext(), null, "mainform");
    Person person = (Person) resolver.getValue(ctx.getELContext(), null, "person");

    //Pretty lengthy SQL stuff here. Commented out. Just wanted to display the display logic below for the dialog.

    if (errorMsg != null) {//If errorMsg is not null, then error occurred.
        showDlgAddress = true;//Ensures address dialog remains open in event of action error.
        queueErrorMessage(errorMsg);
        rctx.update("dlgAddress");
        return;//break out of method on error.
    } else {
        showDlgAddress = false;
        rctx.update("dlgAddress");
    }

    //If everything saves without error, repopulate address and update recordDetails dialog.
    recordDetails.populateAddress(records.getSelectedRecord());
    mainform.updateDlgRecordDetails();

Answer 1

试试这个:

1. 将对话框放在表单中(dialogInputForm)

2. 添加属性update =":dialogInputForm"

3. 将resetInput标记嵌套在打开对话框的按钮中,并将目标指定为刚刚创建的表单

commandButton:

<p:commandButton process="@this" actionListener="#{bean.prepare}" update=":dialogInputForm" oncomplete="thirdPartyDialog.show()" value="Open Input Dialog" >
     <p:resetInput target=":dialogInputForm" />
</p:commandButton>

以及包含对话的形式

<h:form id="dialogInputForm" >
 ... your dialog ...
</h:form>
