Backbone error, Cannot read property 'c18' of undefined <p>I'm making a massive multi page backbone site.</p> <p>I'm sometimes re-using collections and views across multiple pages of the site, as if they were controls. I've now done something which is coming up with errors like this,</p> <p>Cannot read property 'c18' of undefined</p> <p>At the moment, the c18 is always the same.</p> <p>I'm also using backbone relational.</p> <p>Any ideas anyone?</p>
