Column '{colId}' renderer threw during destroy().

Warnings reference › destroy:*

Identifier

destroy:*

Raised by

The grid (rendering)

Since

1.0.1

What happened

A component renderer's destroy() threw while the cell was being released - on scroll, on a re-render, or when the grid was destroyed. The throw is caught so the release continues and the rest of the cell's state is cleaned up, but whatever that destroy() was meant to free may still be held.

The fix

The error is attached to the console line. destroy() is called for cells that were never fully rendered too, so it has to tolerate a half-built instance.
