Error: Method expand is not available in mode "tree"

[jason51553262]

When calling expand() from onChangeMode callback and where mode === 'tree' I get the following error:

Error: Method expand is not available in mode "tree"

The expand method works ok when first mounting the component, but not when switching between modes.

See the issue in the following sandbox:
https://codesandbox.io/s/blue-cloud-i4vo7

On first load the nodes are expanded, but when clicking to code and back to tree, that's when the expand method fails.

Am I calling it correctly?

Thanks for reporting. I did some debugging, and it turns out the onChangeMode callback is called whilst the editor still has to rerender. A workaround is to replace expand() with setTimeout(expand) in your codesandbox.

Fixed now in v0.3.16
