Iron Router, waiting for data

help

EDIT [SOLVED]: I had two entries in the database with the same pathname with one with no text -_-

Hi,
I am stuck with that problem. I am retrieving some data from the database when I jump to a certain route like so:

Router.route('/articles/:name', {
	template: 'articles',
	loadingTemplate: 'loading',
	onBeforeAction: function () {
		Session.set('edit', true);
		this.next();
	},
	waitOn: function () {
		return [Meteor.subscribe('articles', this.params.name), Meteor.subscribe('slides')];
	},
	data: function () {
		return Articles.findOne({pathname: this.params.name});
	},
	action: function () {
		if (this.ready()) {
			return this.render();
		}
	}
});

Here my publishers:

Meteor.publish('articles', function (pathname) {
	return Articles.find({pathname});
});

Meteor.publish('slides', function () {
	return Slides.find({});
});

FindOne bind my articles Template with the data retrieved from the db.
From this data I get the content of a list using an helper’s function.

Template.articles.helpers({
  getParagraph: function () {
	return this[Session.get('lang') || 'fr'] && 
	this[Session.get('lang') || 'fr'].text);
 }
});

The data:

{
en: {
 text: ['some text', 'some other text']
},
fr: {
 text: ['some text in fr', 'some other text in fr']
}

And I display it from my template with {{#each getParagraph}}.

When I navigate through the links, the data renders in the view, but when I access the route directly entering the url manually the list is not filled with my texts yet.
So findOne returns an empty text array.
I think waitOn wait until the subscriptions are ready, but since I could only manage to publish find() and not findOne(),
the view renders without waiting for the data.

I’ll be glad to know were I missed the point. Thanks!
