Can't get the apostrophe utility isEmpty to work

#1

Im using code like this:

                {% if apos.utils.isEmpty(apos.areas.richText(data.page.heroHeadingMobile, { delimiter: ',' })) %}
                    test content {{ apos.areas.richText(data.page.heroHeading, { delimiter: ',' }) }}
                {% else %}
                    {{ apos.areas.richText(data.page.heroHeadingMobile, { delimiter: ',' }) }}
                {% endif %}

But I have also tried like this:

                {% if apos.utils.isEmpty(apos.areas.richText(data.page.heroHeadingMobile, { delimiter: ',' })) %}
                    test content {{ apos.areas.richText(data.page.heroHeading, { delimiter: ',' }) }}
                {% else %}
                    {{ apos.areas.richText(data.page.heroHeadingMobile, { delimiter: ',' }) }}
                {% endif %}

But I never seem to be able to get the else condition to fire:

I am using this inside another condition, not sure if that ok, here is an example of my complete code:

            <h1 class="hidden-sm hidden-md hidden-lg">
                {% if data.page._edit %}
                {{ apos.singleton(data.page, 'heroHeadingMobile', 'apostrophe-rich-text', {
                toolbar: ['Styles','Bold', 'Italic', 'Subscript', 'Superscript', 'Link', 'Unlink'],
                styles: [
                { name: 'Strong Font', element: 'span', attributes: { 'class': 'headline2'} }
                ]
                }) }}
                {% else %}

                {% if apos.utils.isEmpty(apos.areas.richText(data.page.heroHeadingMobile, { delimiter: ',' })) %}
                    test content {{ apos.areas.richText(data.page.heroHeading, { delimiter: ',' }) }}
                {% else %}
                    {{ apos.areas.richText(data.page.heroHeadingMobile, { delimiter: ',' }) }}
                {% endif %}

                {% endif %}
            </h1>

Ok i figured it out.

I need to check the items property.

data.page.heroHeadingMobile.items

instead of:

data.page.heroHeadingMobile

Like this:

                {% if apos.utils.isEmpty(data.page.heroHeadingMobile.items ) %}
                    {{ apos.areas.richText(data.page.heroHeading, { delimiter: ',' }) }}
                {% else %}
                    {{ apos.areas.richText(data.page.heroHeadingMobile, { delimiter: ',' }) }}
                {% endif %}

Seems like nested conditional statements are fine in Nunjucks templates to.
