Disable lazy loading for Node Children in BeanTreeView

[chaddaniels]

I know that the BeanTreeView implements the idea of lazy loading for all Node Children because there can potentially be a huge performance hit for large tree structures. However, this leads to each Node showing an expand-box unless it uses Children.LEAF as its Children object. The real problem is that this expand-box is shown whether or not the Node actually has any children. To me, and some users of my application, this seems misleading because it seems like the expand handle should be shown only when children exist. I know this topic is addressed here but it doesn't offer any solution. So, my question is: Is there a way to disable the lazy loading of children for a BeanTreeView so that all Nodes are loaded when the tree is created?
