Answer 1

Not sure exactly what isn't working, but I might write this as:

{{#each this.model.data as |entity|}}
  <input
    type="checkbox"
    disabled={{(eq entity.workflowTask.id this.currentlyLoggedUserId)}}
    {{on "click" (fn this.getSelectedMerchant entity.id)}}
  />
{{/each}}

First, you need to create a helper. Which check your two ids are equal or not.

import { helper } from "@ember/component/helper";

export default helper(function isEqual(params /*, hash*/) {
const [val1, val2] = params;
return val1 === val2;
});

Then your template you need to do:

{{#each this.model.data as |entity|}}
  <input
    type="checkbox"
    disabled={{(is-equal entity.workflowTask.id 
    this.currentlyLoggedUserId)}} />
{{/each}}
