3284	"Problem with ""when+reinit"" when using vectors"	Henning Kiel	somebody	"The following model implements the bouncing ball model with
1) scalars
2) array of arbitrary length (e.g. 1)

Though both models flatten to the same code (except for the ""[1]"" where appropriate) the model result is different!
