What on earth is "hidden SEPropMediator block"?

Hi,

I have a Simevents model. I have there two Set Attibute blocks. Both blocks get attribute value from Constant block. Constant value blocks get their values from workspace constants. Both values are matrixes (like [1x2] or [3x4]). One block works fine. The other one is L'enfant terrible.

During compile of the model I get this error message: Error in port widths or dimensions. Input port 192 of wsn_simulator_04/SEPropMediatorSESubgraph0' is a [1x2] matrix. This error message is related to a hidden SEPropMediator block. And this error is followed with: Error in port widths or dimensions. Output port 1 of 'wsn_simulator_04/Sensor node09/Const1' is a [4x2] matrix.

Can someone tell what is the mistake I'm doing? Thanks a lot.

This is an internal-only error message and should have been re-worked before being displayed by the product. Please file a Tech Support ticket with a model snippet so that it can be fixed. Thanks.

The message is saying that you are trying to assign an attribute of size [1x2] with a value of size [4x2]. In SimEvents attributes have fixed sizes determined during compile. Somewhere in your model you are assigning an attribute (say "A1") with a [1x2] value and so the product records that the dimensions of A1 is [1x2] and will error out if any other block attempts to read/write a differently sized value from A1.

I've been having this same issue with the mediator prop. I haven't been able to resolve it other than with this issue.
