dede 自定义模型中，有时候新增的字段会报错：

Fatal error:Call to a member function GetInnerText() on a non-object in E:wampwwwincludecustomfields.func.php  in line 539.

解决办法：

打开includecustomfields.func.php文件，找到539行：

把$fvalue = trim($ntag->GetInnerText());

替换成：$fvalue = ($ntag=="") ? trim($ntag) :trim($ntag->GetInnerText());

 就可以了
