FIR decimation sample time

While checking Sample Time colors option, or trying to build the model I get the following error:

Error in 'model_in_school2/FIR Decimation 1': All sample times for this block must be discrete. No continuous or constant sample times are allowed.

My model looks as follow

When I cut the FIR decimation out and check sample time color everything is discrete. How do I fix this error?

OK I manually set sample time of everything before FIR decimation to the value I wanted, instead of inherited (-1).

It works.

Now I'll have to see how it works in dSPACE.
