Filtering TreeGrid with explicitly set data causes exception

[mbach]

Hello everybody,

Usually we use fetchData() to fill tree grids using an associated datasource, but for a single feature I am now required to fill it with a set of records which has been fetched in a regular async method.
I tried to do it like in the showcase samples of tree grids and it works for filling the grid, but when it comes to filtering I keep getting the same error in whatever constellation I try.
The grid shows a loading indicator throws the following error on console:

(6.1.0 / Chrome + Firefox)

I'm not calling getFilteredTree() explicitly. I guess that the tree gets "lost" somewhere causing a "NullPointerException".

What way would you recommend to get a filterable tree grid with explicitly set data?

Thanks in advance!

Make sure you have the latest patched version, and if the error still occurs, try recreating it in a test case we can run to see the problem. Note: if you just enable the filter editor in samples that provide a Tree via setData(), there's no error, so there must be more settings involved.
