So my problem is:
I have a Shape which has some properties
one property is a combobox with the values: "connect" and "disconnect"
If i change the value to "connect" the Model connects to an interface of an PLC. if i save the current status and launch the editor again, the property still says "connect" but i am somehow not able to reconnect to the PLC because i dont know how to read the combobox value at launchtime
