apusic operamasks使用了 w：foreach 迁移到tomcat的问题

aom使用了 w：foreach 迁移到tomcat的问题

如果部署到tomcat的aom应用中使用了 w：foreach，只包含
elite.jar
jsf-api.jar
operamasks-impl.jar
operamasks-options.jar
operamasks-third-party.jar
在一些特殊情况下（w：foreach 绑定的不是一个list对象）是不能运行的，需要加上jstl.jar

uidata.java 方法getDataModel会调用到jstl.jar

复制内容到剪贴板

JAVA 代码:

protected DataModel getDataModel() {
 
   // Return any previously cached DataModel instance
   if (this.model != null) {
    return (model);
   }
 
   // Synthesize a DataModel around our current value if possible
   Object current = getValue();
   if (current == null) {
    setDataModel(new ListDataModel(Collections.EMPTY_LIST));
   } else if (current instanceof DataModel) {
    setDataModel((DataModel) current);
   } else if (current instanceof List) {
    setDataModel(new ListDataModel((List) current));
   } else if (Object[].class.isAssignableFrom(current.getClass())) {
    setDataModel(new ArrayDataModel((Object[]) current));
   } else if (current instanceof ResultSet) {
    setDataModel(new ResultSetDataModel((ResultSet) current));
   } else if (current instanceof Result) {
    setDataModel(new ResultDataModel((Result) current));
   } else {
    setDataModel(new ScalarDataModel(current));
   }
   return (model);
 
  }
