```
int CGXDLMSProfileGeneric::GetData(
CGXDLMSSettings& settings,
CGXDLMSValueEventArg& e,
std::vector< std::vector<CGXDLMSVariant> >& table,
std::vector<std::pair<CGXDLMSObject*, CGXDLMSCaptureObject*> >& columns,
CGXByteBuffer& data)
{
if (settings.GetIndex() == 0) {
data.SetUInt8(DLMS_DATA_TYPE_ARRAY);
if (e.GetRowEndIndex() != 0) {
------here-------
GXHelpers::SetObjectCount(e.GetRowEndIndex() - e.GetRowBeginIndex(), data);
}
else {
GXHelpers::SetObjectCount((unsigned long)table.size(), data);
}
}

fix to for array length

GXHelpers::SetObjectCount(e.GetRowEndIndex() - e.GetRowBeginIndex()+1, data);
```

+++++++++++++++++++++++++++++++++++++++++++++++++++++++++

in PreRead count should be +1 to compare (*it)->GetRowToPdu()
void CGXDLMSBase::PreRead(std::vector<CGXDLMSValueEventArg*>& args)
{
long count = (*it)->GetRowEndIndex() - (*it)->GetRowBeginIndex() + 1;
// Read only rows that can fit to one PDU.

------fix
//if ((*it)->GetRowEndIndex() - (*it)->GetRowBeginIndex() > (*it)->GetRowToPdu())
if (count > (*it)->GetRowToPdu())
{
count = (*it)->GetRowToPdu();
}
GetProfileGenericDataByEntry(p, (*it)->GetRowBeginIndex(), count);
}
