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.
> [SuggestionBox] 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 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
