<editor-preferences> is "potentially dangerous"

Unfortunately, not. This still needs to be done like this. We have to
introduce some better way for registering these hooks.

Thanks for filing this.
Comment 2 Miloslav Metelka 2008-11-24 14:26:50 UTC
IMHO this is a dup of issue 85442.

mmetelka, IIRC this issue was not covered by issue 85442. Issue 85442 is about registering actions, this issue is about
registering hooks under '<editor-preferences>', in this case 'name="kit-install-action-name-list"'. This particular
hook, registers a method that the infrastructure calls to get a list of actions which should be called when the kit is

The problem is that there can only be one kit-install-action-name-list in the system. The last module that registers it
would win I guess.

As Vita said

Lets find a solution in next..
Comment 5 Martin Balin 2016-07-07 07:29:52 UTC
This old bug may not be relevant anymore. If you can still reproduce it in 8.2 development builds please reopen this issue.

Thanks for your cooperation,
