Problem with discretization of SimPowerSystems model using FixedStepDiscrete solver

I am adapting a model for VeriStand simulation which requires this solver: Fixed-step discrete (no continuous states).

When I try to run a simulation I get error:

The "FixedStepDiscrete" solver cannot be used to simulate block diagram 'xxxx' because it contains continuous states

I run the Model Discretizer but it cannot find any continuous blocks. I am using 2012b 32-bit version.

Any suggestions?

Actually I realized I wasn't using discrete RMS. So now its fine. But funny thing is Model Discretizer did not detect the RMS block as continuous. Instead I spotted it with color codes for signals.

Not to mention that the block is right in my face and I didn't pay attention. :)
