Comment (by christinebao):

 Tech diagnosis:[[BR]]
 The defect happens in UnmanagedDataManager.cpp, [[BR]]

 {{{
 int MgUnmanagedDataManager::SubstituteDataPathAliases(string& doc)
 {
     //some code
                     STRING mappingDir = stringProp->GetValue();

                     // replace the mappingName with the actual directory
                     if (!MgFileUtil::EndsWithSlash(mappingDir))
                         MgFileUtil::AppendSlashToEndOfPath(mappingDir);

                     size_t dirLen = mappingDir.length();

                     doc.replace(startPos, len1 + nameLen + len2,
 MgUtil::WideCharToMultiByte(mappingDir), 0, dirLen);
     //some code
 }
 }}}


 mappingDir is STRING type, which stands for std::wstring. However doc
 stands for string and composited by char. So use the size of mappingDir to
 replace the content in doc causing path to be cut off.

 To fix this, mappingDir should be converted to string type first and then
 replace the content in doc.
