Hello All,
   I am calling ReplaceCmd in for loop , where I am replacing one character on textmodel at a time
and applying it's coreesponding attributes.
But after processing some characters ReplaceCmd command failed and indesign get hanged.
 int firstbyte = 0;
 char * splitstr1 = NULL;
 char * fontname1 = NULL;

for(int k =0 ;k < ushortstrlen(pszString);k++)

{
   splitstr1 = (char *)calloc(sizeof(char),10);
   fontname1 = (char *)calloc(sizeof(char),10);
   firstbyte = (int)(pszString[k] & 0x0F00);	
   * splitstr1 = (char)(pszString[k] & 0xFF);

size_t origsize = strlen(splitstr1) + 1;
   const size_t newsize = 100;
   wchar_t wcstring[newsize];
   wcstring[0] = 0;
   mbstowcs(wcstring,splitstr1,origsize);
   K2::shared_ptr<WideString>wide(new WideString(wcstring));
   RangeData rangeforconv(iConvStartat,iConvStartat + wcslen(wcstring));
   InterfacePtr<ICommand>replaceCmd(textModelCmds->ReplaceCmd (iConvStartat,iConvStartat + wcslen(wcstring), wide,kFalse));
   ASSERT(replaceCmd);
   if (!replaceCmd)
   {
	return;
   }
    CmdUtils::ProcessCommand(replaceCmd);

.
   .
   .
   .
   iConvStartat = iConvStartat + wcslen(wcstring);
   .
   .
 }//end of for loop

I trace the values of iConvStartat I am getting it properly in sequence.
For first 3-4 characters it is working properly but after that indesign gets hanged.
