Event Mappings break with Zenpack export/Install

[zenoss]

Problem:

Event mappings break when they are exported to a Zenpack and reinstalled if their ID does not match their Event Class Key, this means that you can not have a Zenpack with more than 1 event mapping with the same class key.

Steps to reproduce:

Create 2 events with the same class Key:

Events -> Mappings -> Pull Down: Add mapping -> ID = test -> OK
test -> edit -> Event Class Key: foo -> Save

Events -> Mappings -> Pull Down: Add mapping -> ID = test2 -> OK
test -> edit -> Event Class Key: foo -> Save

NOTE: Under sequence tab: Both events are the same class key so are in the same sequence!

Create a Zenpack and add the events to it:

Settings -> Zenpacks -> Pull Down: Create Zenpack -> Name = ZenPacks.foo.baa -> OK

Events -> test -> Pull Down: more/Add to Zenpack -> ZenPacks.foo.baa -> OK
Events -> test2 -> Pull Down: more/Add to Zenpack -> ZenPacks.foo.baa -> OK

Export, delete & reinstall the Zenpack:

Settings -> Zenpacks -> ZenPacks.foo.baa -> Pull Down: Export Zenpack -> OK
Settings -> Zenpacks -> Tick ZenPacks.foo.baa -> Pull Down: Delete Zenpack -> OK

From the commandl line:

[zenoss@uktest-rtf-zen01 ~]$ zenpack --install=$ZENHOME/export/ZenPacks.foo.baa-1.0-py2.4.egg
INFO:zen.ZPLoader:Loading

/opt/zenoss/ZenPacks/ZenPacks.foo.baa-1.0-py2.4.egg/ZenPacks/foo/baa/objects/objects.xml
INFO:zen.AddToPack:End loading objects
INFO:zen.AddToPack:Processing links
INFO:zen.AddToPack:Loaded 2 objects into database
INFO:zen.HookReportLoader:loading reports

from:/opt/zenoss/ZenPacks/ZenPacks.foo.baa-1.0-py2.4.egg/ZenPacks/foo/baa/reports
[zenoss@uktest-rtf-zen01 ~]$

Check the sequence of our re-imported events:

Events -> test or test 2 -> Sequence

NOTE: Neither event mapping now has a sequence as they were not imported properly and these event mappings will no longer work!!

Expected behaviour:

The event mappings should be imported exactly how they were added to the Zenpack, i.e: they should be listed in the sequence for their class key and more importantly they should continue to function!

Further testing (I've wasted a day on this!!):

The first event mapping will work IF the mapping ID is the same as the event class key. All other mappings with this Class Key will list this 1 mapping (where the ID==classKey) in their sequence tab bu will not be listed themselves. This might hint to the devs where the problem lies.

NOTE: Please follow the steps in the forum post as they're easier to follow (Trac formatting missed a few new line chars) and a typo in the above has been corrected (setting the event class key to foo for "test" twice instead of "test" & "test2").

I believe this is a duplicate of #3388, but I'm not closing the ticket because I'm not totally sure it is the same issue.

It may be related to 3388, however performing a reIndex after the process listed above does not fix the problem in this case.
