Error: $compile:infchng

Unstable `$onChanges` hooks

This error occurs when the application's model becomes unstable because some $onChanges hooks are causing updates which then trigger further calls to $onChanges that can never complete. Angular detects this situation and prevents an infinite loop from causing the browser to become unresponsive.

For example, the situation can occur by setting up a $onChanges() hook which triggers an event on the component, which subsequently triggers the component's bound inputs to be updated:

<c1 prop="a" on-change="a = -a"></c1>

function Controller1() {}
Controller1.$onChanges = function() {
  this.onChange();
};

mod.component('c1', {
  controller: Controller1,
  bindings: {'prop': '<', onChange: '&'}
}

The maximum number of allowed iterations of the $onChanges hooks is controlled via TTL setting which can be configured via $compileProvider.onChangesTtl.
