I was using custom Handlebars helper extending the functionality of \'if\' block.
In Ember 1.10 this doesnt work anymore as there is no Ember.Handlebars.bind propert
I actually managed to find a way to do it, so I'll write the answer for my own question...
Instead of using undocumented hacks, I used the proposed change: https://github.com/emberjs/ember.js/issues/10295
So my helper looks like this now:
Ember.Handlebars.registerBoundHelper('isSame', function(value1, value2) {
return value1 === value2
});
and the usage:
{{#if (isSame property "value")}}
{{some-other-component}}
{{else if (isSame property "otherValue"}}
something other...
{{else}}
something other...
{{/if}}
