我在我的应用程序中收到以下错误：
错误描述：无法准备搜索结果。
错误消息： [DM_API_E_BADATTRNAME] 错误：“文档/对象的属性名称 'str_en' 错误。”
技术跟踪细节：

仅当我最近将 dfc 从 5.3 (sp6) 升级到版本 6.7 (sp1) 时，该错误才开始。我在本地运行一切。我的 5.3 (sp6) 版本仍然可以正常工作，但我想知道即使它们在同一个文档库、同一个应用程序（dfc 更改除外）和同一个服务器上运行，什么会导致错误。
这是 result.jsp 的代码片段，它应该显示搜索：
<%
java.util.Collection col = null;
se.project.osi.util.dfc.OsiDQL q = new se.project.osi.util.dfc.OsiDQL(org.apache.commons.logging.LogFactory.getLog(this.getClass()));
q.setDQL("select str_en from osi_localized where str_category = 'Title'");
col = q.toCollectionString();
java.util.Iterator it = col.iterator();
while(it.hasNext()){
out.println((String) it.next()+ "<br>");
}
%>
还有search.jsp：
<%
try {
queryBean.parse(request, "");
queryBean.doAction(request, "");
// Get the Query Mgr Model
OsiQueryMgrModel model = (OsiQueryMgrModel) session.getAttribute(IProjectType.MODEL_SEARCH_CONTENT);
String onSubmit = "";
if (model == null) {
// Create new Query Mgr Model
model = new OsiQueryMgrModel();
}
if(request.getParameter("osi_localized.str_en") != null)
onSubmit = "onLoad=\"parent.resultview.location.href = '" +
request.getContextPath() + "/portal/administration/material/resultset.jsp?run=T';\"";
// Assign the updated QueryMgr
model.setQueryMgr(queryBean.getQueryMgr());
session.setAttribute(IProjectType.MODEL_SEARCH_CONTENT, model);
%>
先感谢您，
