I've come across one inconsistency in the DataTable class:
* @return the container with the toolbars at the top
public final ToolbarsContainer getTopToolbars()
* @return the container with the toolbars at the bottom
public final ToolbarsContainer getBottomToolbars()
ToolbarsContainer is defined as private, so those methods cannot be used
anyway. I suggest either changing the visibility of ToolbarsContainer or
removing those methods.
At the moment if I need to refresh toolbars, I have to go via datatable
component's get() method to remove all toolbar items and re-add them again.
