Hi Gabi
As you say, it’s the same log message as in the linked SVY-19171 case in the support system.
What I don’t understand is why appear the getLastDisplayedRow()/getFirstDisplayedRow() messages if they do not exist in NGTi, and we are using NGTi and the latest grids (Data Grid (Servoy NG-Grids)).
Unfortunately I am not allowed to give you a link to our solution and we have no sample. But I hope, the above info helps to come a step further to a solution. May be someone else has a public sample which shows the problem.
Best regards,
