I've come across the same issue in two separate angular projects I've been involved with, but have not been able to find any discussion on this particular problem. This leads me to believe that there may be something I am overlooking. Let's say I have a view of a 'task' which can exist in various states such as 'pending', 'accepted', and 'completed'. Different action buttons will be displayed based on the task's current state, like so:
<button ng-if="task.status === 'pending'" ng-click="ctrl.acceptTask()">Accept</button>
<button ng-if="task.status !== 'accepted'" ng-click="ctrl.acceptTask()">Flag</button>
<button ng-if="task.status === 'accepted'" ng-click="ctrl.flagTask()">Complete</button>
The problem arises when the user clicks the accept button, causing both of the following buttons to briefly appear simultaneously. It seems like Angular is traversing through the DOM sequentially, and during that short interval between ng-if conditions, both the 'flag' and 'complete' buttons are displayed because only one has been updated. This same issue occurs with ng-show.
It's worth noting that this issue cannot be resolved using ng-cloak, as its purpose is solely to prevent template display before Angular processing is complete.
Considering that I’ve encountered this issue in both of the substantial Angular applications I've worked on, it appears to be a common challenge. Any suggestions on how this is typically addressed? (PS: The provided HTML code is just an illustrative example, not my actual template.)
