In the function tau_getOwnIds there is no check that the found fct entery is not a group.
Current sources:
if (ownIP == appHandle->pTTDB->cstInfo[0]->pFctInfoList[index].fctId)
Suggested change:
if (ownIP == appHandle->pTTDB->cstInfo[0]->pFctInfoList[index].fctId && appHandle->pTTDB->cstInfo[0]->pFctInfoList[index].grp == 0)
Changed accordingly. To be tested.
Tested in api_test_4.c test3
