copied!<p>In general, if you have two watchers, D & C that both watch Z, it's best to be explicit about the dependency between D & C, so you don't end up with these ordering issues. </p> <p>I'm not sure if its possible to guarantee the ordering of $watch and other data binding events. But there are a few things you could do.</p> <ol> <li><p>Consolidate</p> <ul> <li>Move your calculation of validity into your regisChange function, instead of using your custom directive. This will be easy in these simple cases where you're only checking a few values. This will eliminate the race condition between your equal directive's $watch handlers firing, and ng-change calling regisChange.</li> </ul></li> <li><p>Be Consistent</p> <ul> <li>You use $watch to check for equality, but then you rely on an event handler to clear an error. Why not $watch both password values and their $valid values (or just the whole input field) so that you can be sure you run your check whenever something changes.</li> </ul></li> </ol> <p>In my mind, it makes sense that the ng-change fires first. It seems to most closely resemble an event handler which I would assume fires immediately after an event, whereas your $watch can only fire after the next $digest() cycle. That being said, it may never be clean to make ng-change and $watch play like how you want them to in this situation.</p> <p>I'm not quite sure what the code is trying to in redisChange function anyway. If you could make a jsfiddle with all of the relevant bits, I could probably be more useful</p>
