I think I know where is your problem. I just compared your code with
Johan code and look what he does in his on_render method:
def on_render(...):
x_offset, y_offset, width, height = self.on_get_size(widget,
cell_area)
So that's why the method on_get_size is called the second time with a
valid value for cell_area.
Hope it helps
Lorenzo
