defaultTraversalAllInstanes() is not traversing instance models

[philip-alldredge]

Hello, I am attempting to traverse all instance models in a workspace using AadlProcessingSwitch.defaultTraversalAllInstances().

Unfortunately, it does not seem to be working. Using the following code, my switch is never called.

final AadlProcessingSwitch generationSwitch = new AadlProcessingSwitch() {
            @Override
            protected void initSwitches() {
                this.instanceSwitch = new InstanceSwitch<String>() {
                    @Override
                    public String caseComponentInstance(final ComponentInstance ci) 
                    {
                        System.out.println("COMPONENT");
                        System.out.println(ci);
                        return DONE;
                    }
                };
            }
        };

        generationSwitch.defaultTraversalAllInstances();

Hi Philip,

Do you have a code sample and a plugin that use this method ? (with a plugin.xml, etc...) ?

[philip-alldredge]

Below are what I consider the relevant files. Let me know if you need something else.
