When trying to assign an item to an alert action (Example: Add to List under Notify HQ User/Notify Roles) the url to Add to List is incorrect. It points to the eid instead of the aetid. Example:
Manually editing the url to:
Will yield the proper results.
Escalations, control actions, scripts seem to be unaffected
Steps to Reproduce:
1- Navigate to Administration - Monitoring Defaults -> Resource - Alerts - Win32
2-Create alert -> select OK
3- Select Notify HQ Users from the tab
4- Select Add to List
5- Select user -> Select OK
User get bounced out to the starting Resouce selection panel with the message "The specified resource does not exist." Adding the user to an escalation and assigning an escalation works as a workaround
Although I couldn't reproduce I believe it's possible for the link to "work" when the aetid equals a valid eid and the user will get added under the incorrect alert. This is why I've marked this with major priority despite there being 2 work arounds.
