I'm creating a TreeList from remote data that will be defined by the end user and that I won't have control over. When I receive data from the data source where parentId = 0, no data loads. When I receive data where parentId = null (for root nodes), the values load successfully.
So...is it required that the parentId value for root nodes be null or is there a flag I can set for the parentId field that says something like "consider nodes whose parentId = 0 to be a root node"?
