We designed Cell based widgets to be as fast as possible, even at the cost of complexity. Our goal is to significantly increase the number of records that an application can show while still having the app feel snappy. The implementations are complicated because we optimize for various use cases, especially in CellTree where there are many states to handle. And of course, all widget designs start simple, and then we have to work around browser bugs. And that's why I stare at the ceiling every night trying to figure out ways to make CellTable faster and simpler (and then curl up in a ball and mumble nonsense).
Still, I acknowledge that the API for CellTree is not as complete as the API for CellTable/CellList, which have received an positive response from most users. After GWT 2.1 was released with the initial version of Cell Widgets, we focused most of our widget efforts on CellTable because that has so much more use than CellTree, so we have not yet addressed the API shortcomings of CellTree. If you have suggestions to make CellTree beautiful like a poem (or even a haiku), please let me know and I'll consider them the next time I do a pass on the API. Suggestions in the form of patch files are preferred.
