I'm getting weird PHP error when using Phalcon's Volt engine in my project. The case seems to be very simple but although I have checked my code many times I can't seem to get working the simple if-elseif-endif structure.
The template code is here, it is placed in Javascript block in context of jQuery callcack function:
{% if table.form.rendered_in == 'offcanvas' %}
            //offcanvas form
            //set attributes
            $(row).find('td.edit-control').
                attr('data-source', '{{table.form.full_action_url}}?get_form').
                attr('data-canvas', 'body').
                attr('data-target', '#rightSlider').
                attr('data-toggle', 'offcanvas').
                click(function () { 
                    console.log('! show edit form: '+record_id);    
                    //edit_one(record_id);
                    if (!right_offcanvas_visible) {
                        //request form with ajax
                        var url = $(this).attr('data-source');
                        var data = {
                            'choose_record': [record_id]
                        };
                        //console.log('Serialized data: '+data);

        {% endif %}The error is generated possibly by Volt compiler at first elseif referenced below, volt file doesn't get compiled into PHP.
{% elseif table.form.rendered_in == 'page' %}The error says: Unexpected ENDIF in .../app/views/partials/grideditor.volt on line 307
The if-elseif-endif structure works nicely elsewhere in Javascript blocks. Which makes things even more odd is that when I replace the elseif with multiple if-endif, if-endif, ... as below, everything works fine.

I'm using Phalcon 1.3.3 TS on Windows (x86, PHP 5.4.19)
Any suggestions are very appreciated! Thanks!
