The combobox selector is not displayed for sequence diagram when using SysML blocks for operations.
Steps to reproduce:
- Create a SysML block called A
- Create a SysML block called B
- Add an operation called myOperation to block B
- Create a sequence diagram
- Drag and drop both A and B to the sequence diagram as a lifeline element
- Draw a message from A to B
- Problem: the combobox where you can automatically select the operation is not displayed
However, this works perfectly with an UML class.
