QAbstractListModel does not get updated with values when data is loaded from CSV, but it does when using hardcoded value

I think the issue was by ths following , I've made a scaled down app in a single script to specifically tackle this problem. Code paste is here. , The problematic code is here:
code :
def load_ROI_table(self):
    ...
    roi_names = [roi_table[x, 0] for x in roi_table_range]
    print(roi_names)
['AC', 'V1', 'M2', 'BC', 'RS', 'M1', 'HL', 'HL2', 'HL3']
print(['%s %r' % (type(i), i) for i in roi_names])
...
["<class 'numpy.str_'> 'AC'", "<class 'numpy.str_'> 'V1'", "<class 'numpy.str_'> 'M2'", "<class 'numpy.str_'> 'BC'", "<class 'numpy.str_'> 'RS'", "<class 'numpy.str_'> 'M1'", "<class 'numpy.str_'> 'HL'", "<class 'numpy.str_'> 'HL2'", "<class 'numpy.str_'> 'HL3'"]
roi_names = [str(roi_table[x, 0]) for x in roi_table_range]

seems to work fine Using hardcoded values for rallymultiobjectpicker is not currently supported, but that option will be available in a future version of the SDK.

I think the issue was by ths following , The way you asked the question makes it confusing. It is possible to make PHP run on all types of files on your server with a bit of Apache tweaking. My solution will make your JS files be processed by the PHP interpreter.
What you need to do is create a .htaccess file if you are using Apache. I am going to assume you are. Then you add this line into it:
code :
AddType application/x-httpd-php .php .js
        <script type="text/javascript">
            var trackFilterFlag = null;
            <?php
                echo "trackFilterFlag = \"". $displayedPageType ."\";\r\n";
            ?>

            var trackFilterCategory = null;
            <?php 

                if(strcmp($displayedPageType, "mood") === 0 || strcmp($displayedPageType, "genre") === 0) {
                    echo "trackFilterCategory = \"". $filterCategory ."\";\r\n";
                } 

            ?>

            var sortingTracksBy = null;
            <?php
                if( isset($chosenSortFlag) && strlen($chosenSortFlag) > 3 && !($defaultSort) ) {
                    echo "sortingTracksBy = \"". $chosenSortFlag ."\";\r\n";
                }
            ?>

        </script>

I think the issue was by ths following , You mustn't declare the dataChanged() signal in your class, because you want to emit the signal AbstractItemModel::dataChanged(). If you re-declare it you add a comleptely new and different Signal that is not connected anywhere. If you remove the declaration in acdata.h everything should work fine.

I wish this helpful for you for @MarkCh for pointing out, that you have not reimplemented the setData()-method.
The signature is:
code :
bool QAbstractItemModel::setData(const QModelIndex &index, const QVariant &value, int role = Qt::EditRole)
bool QAbstractItemModel::setData(const QModelIndex &index, const QVariant &value, int role)
{
    if (index.row() < 0 || index.row() >= m_Devices.count())
        return false;

    const Device &Device = m_Devices[index.row()];
    if (role == NodeIdRole) {
        Device.m_nodeId = value.toInt();
        emit dataChanged(index, index);
        return true;
    }
    else if (role == TypeRole) {
        Device.m_type = value.toString();
        emit dataChanged(index, index);
        return true;
    }
    else if (role == LampVoltageRole) {
        Device.m_lampVoltage = value.toInt();
        emit dataChanged(index, index);
        return true;
    }
    return false;
}
onClicked: model.nodeId = 100;
Why the jsf view is not updated after new data in the backing bean are loaded from database?

hope this fix your issue
It seems just like the view is rendered before that the backing bean has completed its updates.
