It happens in a new project.
I installed TMS WEB Core using TMS Smart Setup. If I search within the Products/tms.webcore folder for *.pas files containing TGoogleChartDataPoint I find 2 of them:
...\Products\tms.webcore\Component Library Source\WEBLib.GoogleChart.pas
...\Products\tms.webcore\Core Source\WEBLib.GoogleChart.pas
And they are different! Is that normal? In noticed that in class TGoogleChartSeriesValueItem, in the first file property DataPoint is public, but in the second file it is published. Could that be the problem?
I also noticed that I have 2.9.1 installed and 2.9.3 is available. I could upgrade if that might help.
Thanks!
