stl 编译错误问题,急急急!!!

[myseven]

程序中有段代码如下:
CHLAObject* CRecorder::getObjInstance(RTI::ObjectClassHandle handle)
{
map<RTI::InteractionClassHandle, CHLAInteraction*>::iterator res = this->objectClassHandleMap.find(handle);
.....
};

其中:CHLAObject是一个类,RTI::ObjectClassHandle是一个整形数,为啥编译的时候这段报错如下:
d:\vc projects\Recorder\Recorder\Recorder.cpp(15) : error C2440: 'initializing' : cannot convert from 'std::_Tree<_Traits>::iterator' to 'std::_Tree<_Traits>::iterator'
with
[
_Traits=std::_Tmap_traits<RTI::ObjectClassHandle,CHLAObject *,std::less<RTI::ObjectHandle>,std::allocator<std::pair<const RTI::ObjectClassHandle,CHLAObject *>>,false>
]
and
[
_Traits=std::_Tmap_traits<RTI::InteractionClassHandle,CHLAInteraction *,std::less<RTI::ObjectHandle>,std::allocator<std::pair<const RTI::InteractionClassHandle,CHLAInteraction *>>,false>
]
No constructor could take the source type, or constructor overload resolution was ambiguous

百度了些帖子, 试了些方法都不好使..求助!!!!
谢谢!!

map<RTI::InteractionClassHandle, CHLAInteraction*>::iterator
和this中的类型一样么

[liujiwei2007]

cannot convert from 'std::_Tree<_Traits>::iterator' to 'std::_Tree<_Traits>::iterator'

这两者类型是一样的啊

知道了,我看错了...-_-||谢谢各位
