i'm trying to use the TMSFNCStateManage component but i can't compile.
The error is [Erreur] WEBLib.TMSFNCStateManager.pas(924): identifier not found "RemovePair" pr := (oa[J].FParentValue as TJSONObject).RemovePair(oa[J].FValueName);
I retested this here but I cannot see an issue.
Again, are you 100% sure you have a clean setup of the latest TMS WEB Core version, i.e. no old TMS WEB Core version files on your system?
