Can't get valid result from ClntObjMgrObjectPtr?

[rik.chong]

Hi

I'm using ClntObjMgrObjectPtr to get object pointer by GUID. It worked fine with 18414, but something wrong with 19034.

WoWGUID guid(...); // holding a 128bits new format guid
CGObject_C *pObj = ClntObjMgrObjectPtr(guid, -1);

I got the correct pointer with 18414, but get invalid one with 19034, such as 0x0000000E 0x0000000D. Need to change the filter param? I tried filter with value '1', resulted 0x00000000.
And I'd tried to set a BP within ClntObjMgrObjectPtr, but never got called, confusing;(

Any idea?
Thanks in advanced.

I meant ClntObjMgrObjectPtr never got called in game, my own call for sure can be followed.
