Since we deploy with Developer version 2024.3.3 and as NGTi, we get in the Server Log quite a lot of the following grid warnings (attached screenshot):

Sometimes it references get **Last** DisplayedRow(), sometimes get **First** DisplayedRow().

A similar warning is given in the Developer Console.

I can’t find out “who” destroys the grid.

Regards,

While debugging, we found:

- All forms inherit from a super form and call \_super.onShow(…)
- The super form adds buttons onShow and calls recreateUI
- Did not happen in 2022.06 NG

It is the same as reported in this case [https://servoy-cloud.atlassian.net/browse/SVY-19171](https://servoy-cloud.atlassian.net/browse/SVY-19171) but Servoy NG Grid is not using getLastDisplayedRow()/getFirstDisplayedRow() in TiNG, and that is a log from a TiNG client, right?  
Can you create a (private) case for this, and add a link to (a sample of) your deployed app so we can debug it?

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,
