Hi, we have 2 tree grids in our application. Both successfully used the expand all and collapse all that is provided on the toolbar. But at some point in the last 1 1/2 weeks, this function stopped working.
Here is the error:

core.js:5847 ERROR TypeError: Cannot read property 'index' of undefined

We are not using any custom code for this, just the toolbar functionality. We have Collapse All added to the toolbar options. All other toolbar options such as pdf export, excel export, add, edit, delete are working.
Thanks in advance for the help!
