[HTMLBars] Bind more controller properties to one attribute

Hi,

is this correct or is there any other solution?

<input disabled={{model.isnValid}} disabled={{isSaving}}>

I know that I can create new CP and depend on model.isnValid and isSaving, but I want to know if there is any other solutions.

Thank you for advices

Not that I know of. is there some reason that you don’t want to use a computed property?

No, I used CP, but I wanted to know about other possibilities.

I found ember-truth-helpers - npm but CPs are much better in this situation.
