Failed to change the Mask value of Simulink Subsystem in R2020b.

I opened a Simulink model which is built in R2020a, it has a subsystem, and some parameters are given by the mask of this subsystem. It work well in R2020a, but I just cannot successfully change any value though the mask GUI, which means I put a new value in the box, and press the apply button, everything appears normal, but the value of mask are not actually changed. If I open the mask again, the value returns to the previous value. The only way I find in 2020b to do so, is get into the mask editing scheme, and value can be actually changed.

I think it is kind of new bug introduced in R2020b.

And I hope it can be fixed in time.

Hello Xianshan,

Please tell me the model name of the built-in you used.

Hello stozaki,

This is not a built-in block problem, It happend when I build a new mask.

I try to figure it out, so I build a new model today, and it is related with the prompt of "edit" in Parameter&Dialog.

If the prompt is in English, mask works fine, but if the prompt is in Chinese, I just cannot change the value.

Like in the figure below, the first parameter can be changed, while the second parameter can not.

The .slx file is also uploaded, I just hope this bug can be fixed.

Hello

We apologize for the inconvenience.

I understand your problem. And I also reproduced the problem you pointed out in R2020b. Past MATLAB versions have not had this problem. Perhaps there is a bug specific to R2020b.

Did you request this issue in your service request? I could report this issue to the development team instead. Can I report a bug?

Best Regards,

stozaki

I didn’t report this issue, please report this bug. Thank you.
