Nested Rows, Auto Row Size and Fixed Rows Bottom

Tags: #<Tag:0x00007fd2bd852248>

Hello,
I have identified another issue with nested rows

https://jsfiddle.net/awbL035m/

The combination of Nested Rows+Auto Row Size+Fixed Rows Bottom gives an error on collapsing all or expanding collapsing children.

Thank you for sharing @martin

I simplified the example https://jsfiddle.net/7d3wxzaL/ and it looks like attaching data directly in the data (not by a server call) also solves the issues.
It might be related to the process of constructing a table based on the loaded data (data manager error).

Have you tried to load data first (to a variable) and then pass it to Handsontable in data?
