Cannot register run-time parameter for dialog parameter XX for S-function 'sf_sfun' error while compiling simulink model with stateflow chart
显示 更早的评论
I am developing a simulink model which includes a stateflow chart, while doing an update diagram, I am getting the following error.
Cannot register run-time parameter for dialog parameter 15 for S-function 'sf_sfun' in XXModule Stateflow chart nameXX because the dialog parameter is empty. The same error exists for different dialog parameter numbers. Is it something related to data dictionary, and where do I find the dialog parameter numbers?

Same, is it a bug ? I'm using MatlaB 2022B, impossible to find which data stateflow refer to. Only way seems to restart from scratch.

You need to check your simulink parameter. Which the Datatype shall not be auto and the value shall be []
