Nick Belaevski resolved RF-6456.
--------------------------------

    Resolution: Rejected


Both calls are necessary, because they call suggestion action with two different arguments. Suggestion box itself is not capable on filtering returned values, so we cannot use a single call.
You can switch off this feature.

> 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 UiSuggestionBox.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
