How to fix failed assertion in b:\matlab\​toolbox\st​ateflow\sr​c\stateflo​w\utils\ob​ject.cpp at line 2861: object[id]!=NULL

Hi,

I created a stateflow model which was working fine previously. but Nw if i make any changes in model(even if i delete a commented line) i'm getting this error.

Parsing failed for machine: "modelname"(#21)

failed assertion in b:\matlab\toolbox\stateflow\src\stateflow\utils\object.cpp at line 2861:

object[id]!=NULL

Any help would be really appreciated.

Thanks!

Hi Cicily,

This issue would occur when you open a model in your version of MATLAB that was originally created in a different MATLAB version.

As a workaround, you can try one of the following options:

1. Copy and paste the model containing the chart into a new Simulink model and then simulate it.
2. Open your model in the MATLAB version in which it was created, export it to MATLAB R2013b, and then simulate the model in MATLAB R2013b. The model should then simulate without any errors."

Hope this helps!!
