Trait method availableFields has not been applied, because there are collisions with other trait about nova-mega-filter

[4n70w4]

Workaround:

    use HasResourceNavigationTabTrait, HasMegaFilterTrait {
        HasMegaFilterTrait::availableFields insteadof HasResourceNavigationTabTrait;
    }

By doing your workaround the HasResourceNavigationTabTrait will not work properly, Its better you create a subclass that implements this trait and extends it so you can have both functionalities working simultaneously

@milewski you're right! Updated workaround:

    use HasResourceNavigationTabTrait {
        availableFields as rnAvailableFields;
    }

    use HasMegaFilterTrait {
        availableFields as mfAvailableFields;
    }
