Runt-time errors when displaying a grid

Fletcher_Alan · June 10, 2026, 2:27pm

After updating my components to the latest components I started to get the following errors when I display a grid on a form in a TMS Web Core application. This seems to be coming from the components and not any logic that I have implemented.

WEBLib.Dialogs.pas:1550 Uncaught NotFoundError: Failed to execute 'removeChild' on 'Node': The node to be removed is not a child of this node.

Sorry. I neglected to state that this is a FNCGrid.

brunofierens · June 11, 2026, 11:41am

I'm sorry but we'll really need more details on how you use the grid. What properties, event handlers, methods you call, use it with a DataAdapter or not etc...
A good first test to see if your environment is setup correct would be to check our included demos if these work out of the box.
