Stateflow issue in code generation: Invalid chart_inlinable property

I tried to generate code for a Simulink model, and I had this message:

Error using rtwbuild (line 228) Error calling generated SFunction, BiCbiFli_Pcupwmx_sfun. Stateflow Internal Error: rtw_optimization info did not return a valid chart_inlinable property

Error in sl_customization>GenerateCode (line 308) rtwbuild(subSys,'Mode','ExportFunctionCalls');

Error in sl_customization>callGenerateCode (line 238) GenerateCode(subSys);

Do you know how to solve this issue? Where can I find this property?

Thanks,

This seems like a bug. Please contact MathWorks Tech Support to see if they can provide a workaround.

Did you manage to find a solution to this problem?

I am experiencing somewhat the same issue when generating code with rtwbuild.

   Error using runModel (line 12)
      Error calling generated SFunction, mymodel_sfun. Stateflow Internal Error:
      rtw_optimization info did not return a valid chart_inlinable property
      Error using runModel (line 12)
      Error while bringing model references of model combinedTest up to date: Error
      calling generated SFunction, mymodel_sfun. Stateflow Internal Error:
      rtw_optimization info did not return a valid chart_inlinable property

However, if I clean the work folder, run the model in Accelerator mode and then use rtwbuild afterwards, it works. As if the accelerator build succeeds, and rtwbuild uses the generated files.

I am using many referenced models. I don't know if that could cause an issue.

Anybody have any insight? I am having a very similar issue...

This isn't a great solution, but, I've found that if I call 'rtwbuild' on the offending sub-block (model reference) after the failed build, then when I try to build the full model it will go through. I.e., in your example, you could call rtwbuild('mymodel')
