Finally!!!! I nailed the height bug! So, now you can finally make advantage of the variable row height! After a lot of searching, setting debug statements and all other debugging stuff, it turned out one event was called a bit too much which caused flex to seriously fuck up. Still can’t find the exact reason for it, but removing the listener did not harm the tree at all, so it was useless anyway .

You can download the new swc from the project page, which is here. Also, a link to the docs and an example can be found on the project page

Have fun!
