I'd make it so that there is a static port and its connectable, and the visible parts of the symbol for the static port are conditional. Add an extra 'error' element (e.g. a bold red exclamation mark) in the same position, and set its condition to display when the static port shouldn't be visible AND there is a role connected to that port.

In this way, you're also covered for the case where the port's condition is initially true, the user connects to it, and later the condition becomes false.

I have an object in which a property is specified. If the property has a certain value I must connect another object to it, and otherwise not. So I want a connectable (With a port attached to it)  to be visible dependent on the property (and also the binding must only be possible in the relevant case).

In the symbol editor I can choose Format > Condition and then specify the condition source for a rectangle or an ellipse, but not for a connectable.
Probably I have to use a dynamic port for it (naming sounds logic) but I only come across difficult examples with subgraphs. 

What would be the most easy way to get this done?
