我是primefaces dynaform的新手，我只是构建了一个简单的网页并且弄错了。我有2个按钮，它们将生成不同的动态变形。它用第一个按钮运行井，但是我无法点击第二个按钮，并且出现了错误
java.lang.IllegalArgumentException: Either HTTP 500 or java.lang.Throwable error page is required in web.xml or web-fragment.xml. Neither was found.

@ManagedBean(name = "processInstanceBean")
@SessionScoped
public class ProcessInstanceController implements Serializable {
private DynaFormModel model = new DynaFormModel();
public void testDynaform2() {
model = new DynaFormModel();
DynaFormRow row = model.createRegularRow();
DynaFormLabel label11 = row.addLabel("LABEL2");
DynaFormControl control12 = null;
control12 = row.addControl(new BookProperty("2", false), "input");
label11.setForControl(control12);
}
public void testDynaform1() {
model = new DynaFormModel();
DynaFormRow row = model.createRegularRow();
DynaFormLabel label11 = row.addLabel("LABEL1");
DynaFormControl control12 = null;
control12 = row.addControl(new BookProperty("1", false), "input");
label11.setForControl(control12);
}
答案 0 :(得分：-1)
删除immediate="true"并在命令按钮中使用process="@this"。
