It's expecting an int for the row to insert the string. Also it doesn't
return a string:
http://www.webtoolkit.eu/wt/doc/reference/html/classWt_1_1WStringListModel.html#a3bf0b8d2e110cbd518a57f74e8f9e4c6
so you could change the line from:
tuple->store = "A: " +
Wt::WStringListModel::insertString(strl).toUTF8();
to:
tuple->store = "A: " + strl.toUTF8();
Wt::WStringListModel::insertString(ROW_NUMBER, strl);
Where ROW_NUMBER is the number of the row you want to store it in .. or more
likely you'll want:
tuple->store = "A: " + strl.toUTF8();
Wt::WStringListModel::addString(strl);
Maybe strl is empty ?

All of the data generated in your IT infrastructure is seriously valuable.
Why? It contains a definitive record of application performance, security
threats, fraudulent activity, and more. Splunk takes this data and makes
sense of it. IT sense. And common sense.
