State machine graphical interface refuses to draw some transitions


I’m trying to draw transitions between a nested state and its parent state (which is possible according to the UML standard), but the graphical interface won’t let me do such a thing (once in a few attempts the transition however appears…)

Could you tell me how to proceed to get those transitions drawn?

Thanks a lot

PS : it seems impossible to register into your forum (java.lang.NullPointerException)

Hi Jean,

Thank you for your post and sorry for my late reply. I read through the specification but failed to locate the part you mentioned. Do you mean the image that looks like the attached one? If not, could you tell me the page number in the specification for me to check in detail.

Finally, would you mind trying to register again and post the null pointer exception if it appears? I tried to create account, but failed to find any problem. Thank you.

Best regards,
Jick Yeung
