SuggestionAction called twice during request if usingSuggestObjects = true
--------------------------------------------------------------------------

                 Key: RF-6456
                 URL: https://jira.jboss.org/jira/browse/RF-6456
             Project: RichFaces
          Issue Type: Bug
    Affects Versions: 3.3.0
            Reporter: Gerrit Brehmer


SuggestionAction is called twice, if usingSuggestObjects is activated. I looked into the sourcecode and found the two calls:

# Action with value from request/input field (method setupValue - setValue(suggestingAction.invoke(context.getELContext(), new Object[]{submittedValue}));)
# Action with "null" as string (method getRequestValuesData - setValue(suggestingAction.invoke(context.getELContext(), new Object[]{requestedValue}));)

(SourceCode from UiSuggestionAction.java Tag 3.3.0)

Is the second call really necessary? Because we call an expensive backend method (200ms - 7000ms for address suggest) this makes a noticable delay for the user

Our workaround is to return an empty list for the second call, which doesn't change the behaviour
