But since it's more a GXT 3 issue, I (re)post it in this section.
Are there any updates? My TreeGrid contains about 600 entries in 3 tree levels. Collapsed state is not a problem, but the TreeGrid has to be fully expanded. The created DOM is huge, so the component is not really usable (expand all = 15sec, expanding/collapsing one RootNode = 8sec). Buffered loading like in LiveGridView would be great. Is such a component planned? Or is there any other way to solve that problem?
