ConfigurableNavigationHandler get navigation case for combination of outcome and origin action

Question

As seen in this question Programmatically get navigation case <to-view-id> from faces-config.xml by outcome i use getNavigationCase to get my view id based on the outcome, and in my case also on the fromAction.

    FacesContext context = FacesContext.getCurrentInstance();
    ConfigurableNavigationHandler configNavHandler = (ConfigurableNavigationHandler) context.getApplication()
            .getNavigationHandler();
    NavigationCase navCase = configNavHandler.getNavigationCase(context, fromAction, outcome);

The problem is no navigation case is found, even if i have a navigation case matching perfectly fromAction and outcome

<navigation-rule>
    <from-view-id>/jsp/example/exampleSource.xhtml</from-view-id>
    <navigation-case>
        <from-outcome>loadSuccess</from-outcome>
        <to-view-id>/jsp/example/exampleDetails.xhtml</to-view-id>
    </navigation-case>
    ...
</navigation-rule>

It happens only with the navigation rules with a from-view-id field. The simpler ones work. Example:

    <navigation-case>
        <from-outcome>GOTO_SEARCH</from-outcome>
        <to-view-id>/jsp/search.xhtml</to-view-id>
    </navigation-case>
