Problem with the Manager::GetValueListValues method

[igorlopez]

Hi,

Since the python-openzwave repo is running on the 1.4 version and I really need the 1.6 version for my Fibaro button I have been trying to modify the example app, MinOZW, to see if I can make my app in C++ instead of Python.

Anyway, I have modified main.cpp to the point it actually runs but I am not getting any values in my notification callback where I am using the Manager::GetValueListValues method.

The function call returns True but when looping over the values they are all 0 which does not match what the button is sending.
Code part printing read values:

printf("#¤#¤#¤#¤#¤#¤#¤#¤#¤#¤#¤#¤#¤#¤#\nButton pressed\n");
for(list<ValueID>::iterator it = nodeInfo->m_values.begin(); it != nodeInfo->m_values.end(); ++it)
{
    // check for correct ValueId
    if((*it) == _notification->GetValueID())
    {
        printf("\tFound ValueId\n");
        ValueID v = *it;
        const ValueID& vRef = v;
        vector<int32> values;
        if(svea_mgr->GetValueListValues(vRef, &values))
        {
            for(vector<int32>::iterator it2 = values.begin(); it2 != values.end(); ++it2)
            {
                printf("\t\t Value: %d\n", *it2);
            }
        }
    }
}

Printed in Console:

Logging from Value.cpp shows that the value is updated and for each press (except the first press which is above) one sees the first message (button pressed down with old_value=0, new_value=1 and then when button is released it prints the reveresed.
So for some reason does my usage of the GetValueListValues not get the expected value.

I am assuming that the vector has 8 elements since during init there are 8 ValueAdded notifications, 3 COMMAND_CLASS_BASIC and 5 COMMAND_CLASS_SWITCH_MULTILEVEL:

2021-08-21 10:50:35.446 Detail, Node002, Notification: ValueAdded CC: COMMAND_CLASS_SWITCH_MULTILEVEL Instance: 1 Index: 4

Maybe I am using wrong API but then I have no idea on what to use instead.
The ValueId returns that it is a list which is why I chose the GetValueListValues method.

So either I am using the wrong API or something is not ok in the library.

I am attaching the console output since it has some more printouts than OZW_Log.txt and my modified main.cpp in case it is something else.
