I've installed and configured Openfire server with Monitoring Service Plugin, in order to keep chat history.
When users are chatting in a public room, all chat messages are saved in the database, and I can see them when I select rows from belonging MySQL table.
One of my requirements is to enable users to see his "old" messages. To able to do that, IQ Stanzas has to be sent, which is really well explained on the following link: http://xmpp.org/extensions/xep-0136.html#manage
My IQ Stanza looks like:
<iq type="get" id="pref1" xmlns="jabber:client">
<retrieve xmlns="urn:xmpp:archive" with="[email protected]" start="2016-07-11T06:27:45.140Z">
<set xmlns="http://jabber.org/protocol/rsm">
<max>30</max>
</set>
</retrieve>
</iq>
For that IQ Stanza, I receive the following output:
<iq xmlns="jabber:client" type="result" id="pref1" to="testuser@kfm/b2yg0qj04r">
<chat xmlns="urn:xmpp:archive" with="[email protected]" start="2016-07-29T13:45:24.245Z">

Question 1
Only message body is returned in chat history, but not message attributes (for example when I send a message, I set additional attributes to it, and I need them in this chat history). Is there a way to enable this feature?
Question 2
Why the same message is returned multiple times? In my case, every message is returned 3 times, although, I sent message only once?
