Public bug reported:

Hi everyone,

I suspect we have a bug with the widget system. I can't make it work
with the t-foreach in qweb, when I try I have the following error

Error: QWeb2 - template['VoteFiveStar']: Runtime Error: Error: QWeb2 -
template['VoteFiveStar']: No enumerator given to foreach

Here is my javascript file :

openerp.web_widget_vote = function(instance) {

instance.web.form.VoteFiveStar = instance.web.form.FieldChar.extend({
    template: 'VoteFiveStar',

    start: function() {
        this._super();
        this.votes = ["test", "test"];    //this.get('value');
    },

});

instance.web.form.widgets = instance.web.form.widgets.extend({
    'vote_five_star' : 'instance.web.form.VoteFiveStar',
});

};


And my template file :

<?xml version="1.0" encoding="UTF-8"?>
<templates id="template" xml:space="preserve">
<t t-name="VoteFiveStar">
        <t t-foreach="widget.votes" t-as="vote">
<p><t t-esc="vote"/></p>
        </t>

    <span class="oe_form_field oe_form_field_vote_five_star">
        <a t-att-name="widget.name" string="-2" class="oe_e star_vote_five_star oe_star_off">7</a>
        <a t-att-name="widget.name" string="-1" class="oe_e star_vote_five_star oe_star_off">7</a>
        <a t-att-name="widget.name" string="0" class="oe_e star_vote_five_star oe_star_off">7</a>
        <a t-att-name="widget.name" string="1" class="oe_e star_vote_five_star oe_star_off">7</a>
        <a t-att-name="widget.name" string="2" class="oe_e star_vote_five_star oe_star_off">7</a>
        <a t-att-name="widget.name" class="oe_e ok_vote_five_star" style="display:none;">8</a>
    </span>
</t>
</templates>

If I replace the foreach by a 
<p><t t-esc="widget.votes"/></p>
I have no more the error message and I have a "test,test" displayed, so the variable is clearly passed to the template.


I don't understand what is happening... And it's seems I'm not the only one :

No answers on all theses tickets until now, there is definitely
something which is wrong.
