save states of a digital filter

Hi,

I have a Simulink model with a Digital Filter and a system. The final states of the model are stored in xStart. When I run the model without initialization var the system and the filter need a while to engage (transient oszilations). For the second run I use xStart as initial state var. Where as the system continues where it ended in the first simulation, the filter needs to engage again. The xStart var contains structures that reference to the filter. Therefore, I would expect that the filter is able to continue with the last state as well.

Why is this not the cases?
