Hello,

The executeAsynch method for your activity is called with a
Map<String, T2Reference> which gives the values sent to the input ports
of the activity. Assuming your activity has a map of defaultValues, you
need to do something like:
private Map<String, Object> defaultValues = new HashMap();
...
public void executeAsynch(final Map<String, T2Reference> data,
final AsynchronousCallback callback) {
callback.requestRun(new Runnable() {
public void run() {
...
Map<String,Object> actualInputs =
new HashMap<String,Object>(defaultValues);
for (String key: data.keySet()) {
Object value = referenceService.renderIdentifier(data.get(key) ...);
actualInputs.put(key, value);
}
....
}
}
}
I'd expect that the default values are part of the configuration, so the
configure method will need to populate the defaultValues map.
