The getChildren() in HierarchicalDatasource does its job as designed. I call it with a row in a Hierarchical TreeTable and it correctly returns a Collection of children of the row.
Since this row further has grandChildren, what I really want is to return ALL entities down the hierarchy, including children, grandChildren, grandChildren’s children …, i.e., a method of getChildrenRecursively() would be nice.
I can try to implement the recursiveness but I noticed this feature has been added to GroupTable in platform version 6.3.0:
I am wondering if any plan adding this feature for TreeTable in the future release?
