problem

If a user starts a replace all action which runs for a longer time, and he leaves the task or logs out, that produces on PHP side:

ZfExtended_NoAccessException: In the meantime, the task was opened in read-only mode.

And if he leaves the task (not log out) in JS:

Uncaught TypeError: Cannot read property 'setLoading' of undefined
at constructor.showReplaceAllLoading (SearchReplace.js?_dc=1566282172714:1737)

solution

Fire an event beforeLeaveTask where for example search and replace can listen for. If a search and replace request is running, the beforeLeaveTask should return false so that the task leave can be interrupted.
