Ember Uncaught TypeError: Cannot read property 'yield' of undefined

Question

We are getting an error Uncaught TypeError: Cannot read property 'yield' of undefined for the following hbs code;

<button {{if isButtonEnabled 'enabled' 'disabled'}}>Test</button>

isButtonEnabled is a property defined on my corresponding controller

Answer 1

You'll have to flip your condition and do this. I just had this exact problem and this was the solution.

<button disabled={{isButtonDisabled}}>Test<button>
