tree.loadChildren failed for "{key}": {error}

Warnings reference › tree.loadChildren

Identifier

tree.loadChildren

Raised by

The grid (core)

Since

1.4.0

What happened

A lazily-loaded tree branch failed to load. The branch is deliberately *not* marked as loaded, so collapsing and re-opening it retries - a failure the user can recover from is better than a branch that is permanently empty. A tree:loadFailed event is emitted alongside this line.

The fix

The error's message is quoted in the line, and the event carries the error object for your own retry or reporting.
