Here is the FAQ page of the SAM Tools.
- I can not change the name of a Port in the diagram area ?
- The text associated with a Port in the editing window is in fact the name of the Flow connected to. When the Port has just been created and that it is not connected to a Flow yet, this is the name of the Port that is displayed and the label is still Editable. But once the Port is connected to a Flow, the label is not editable anymore. To change it, you should select the Flow and change its name in the Properties View : this will update the label of all the Ports that are connected to.
- How can I display the priority of a Transition in an Automaton Diagram ?
- The priority of a Transition is displayed when its value is different of '0'. By default, the priority of the Transition is set to '0', so it is not visible. You have to change it in the Properties View.
