Question

我在新的Scout Neon工作，我开始收到错误：

Assertion error: Property 'modal' cannot be changed because Form is already showing

我的表单有属性：

@Override
protected int getConfiguredModalityHint() {

   return MODALITY_HINT_MODELESS;
}

@Override
protected int getConfiguredDisplayHint() {

   return DISPLAY_HINT_VIEW;
}

@Override
protected String getConfiguredDisplayViewId() {

  return VIEW_ID_CENTER;
}

我做错了什么？

编辑：Marko

我在MyOutline中添加页面，从AbstractOutline

延伸

public class MyOutline extends AbstractOutline {

  @Override
  protected String getConfiguredTitle() {

    return TEXTS.get("MyOutline");
  }

  @Override
  protected void execCreateChildPages(final List<IPage<?>> pageList) {

    final MyPage myPage = new MyPage();

    pageList.add(myPage);
    super.execCreateChildPages(pageList);
  }
}

MyPage只是表单的包装页面。

public class MyPage extends AbstractPageWithNodes {

  @Override
  protected boolean getConfiguredLeaf() {

    return true;
  }

  @Override
  protected boolean getConfiguredTableVisible() {

    return false;
  }

  @Override
  protected String getConfiguredTitle() {

    return TEXTS.get("MyPage");
  }  

  @Override
  protected Class<? extends IForm> getConfiguredDetailForm() {

    return MyForm.class;
  }
}

我的表格没什么空间的：

@FormData(value = MyFormData.class, sdkCommand = FormData.SdkCommand.CREATE)

公共类MyForm扩展了AbstractForm {

  /**
   * Method start Form for adding new person.
   */
  public void startNew() {

    this.startInternal(new NewHandler());
  }

  @Override
  protected boolean getConfiguredAskIfNeedSave() {

    return false;
  }

  @Override
  protected int getConfiguredModalityHint() {

    return MODALITY_HINT_MODELESS;
  }

  @Override
  protected int getConfiguredDisplayHint() {

    return DISPLAY_HINT_VIEW;
  }

  @Override
  protected String getConfiguredDisplayViewId() {

    return VIEW_ID_CENTER;
  }

  public MainBox getMainBox() {
 ...

但是当我想打开这个页面时（在此页面上没有打开启动应用程序），（之前我没有做任何其他事情）我得到了错误。

我找到了解决问题的方法。

在我的构造函数中，我有：

public PersonsExtensionFieldForm() {
    this.startInternal(new NewHandler());
}

女巫没问题，当你打开其他表格的表格时，例如点击按钮。

但是当您将表单作为Detail表单放在页面中时，您需要

 public PersonsExtensionFieldForm() {
    this.setHandler(new NewHandler());
 }
