oracle.jbo.NoObjException：JBO-25003：Object 找不到类型DataControl

Question

当我尝试在Tomcat 8.5.24和JRE 1.8.0_201上运行Oracle ADF时，我收到以下异常。

oracle.jbo.NoObjException: JBO-25003: Object <ObjectName> of type DataControl is not found.

当我打印BindingContext.keySet()的键时，我看到未找到的<ObjectName>，但它具有以下名称结构<ObjectName>@<Path_to_databindings>_DataBindings_cpx。任何帮助，将不胜感激。

Answer 1

我使用以下代码以编程方式找到了此错误的小解决方法;

BindingContext bc = // Load BindingContext
for (Object k:bc.keySet()) {
    if(k.toString().endsWith("@<Path_to_databindings>_DataBindings_cpx")) {
        String newKey = k.toString().substring(0, k.toString().indexOf('@'));
        bc.put(newKey, bc.get(k));
    }
}
