Message archiving and XEP-0004: Data Forms. How to retrieve custom fields?
Hi,
I try to archive custom messages using Message Archiving component. At the beginning I try to archive messages in format:
<message to='20@localhost' from='1@localhost' id='dyP9g-18'>
<subject>Hi</subject>
<body>Message body</body>
<custom xmlns='http://my.namespace.com'>
<name>000000003659</name>
<surname>15</surname>
<date>1374144203775</date>
</custom>
</message>
The above message is correctly stored in database and delivered to recipient. But when I retrieve messages via archiving component then custom fields disappear. I thought that it may be caused by custom nature of my message so I decide to use XEP-0004 standard (Data Forms). But behaviour is the same. Here is a detailed description:
- My database content (sorry for formatting):
+----------+----------+---------------------+-----------+------+------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+
| owner_id | buddy_id | ts | direction | type | msg |
+----------+----------+---------------------+-----------+------+------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+

- My XMPP request for getting archived messages:

Now you can see that second message contains no XEP-0004 form fields. Is it possible to retrieve via archiving component original message? I can use first or second approach.
P.S.
I am using Tigase 5.2.0 version and in reality data inside custom messages are a little bit more complicated.

Currently Message Archiving component implementing XEP-0136 stores full message stanza in database but it is only possible to retrieve <body/> part of a message. It is possible to extend it be able to retrieve whole message stanzas as chats items, but it is not implemented right now, as Message Archiving component was considered to be a component which stores only chat messages, and due to that it requires message to contain <body/> element.
If you would like to see this feature added in next release, fill free and create a new issue for Tigase Message Archiving project.

Thank you, I assigned Andrzej to the ticket as he is the component author.

Please verify that you properly upgraded installation to snapshot version. I just used tigase-message-archiving.jar from a build you mentioned and I received correct results. I see that you still are receiving wrong first, last elements in response - which suggests that something went wrong during upgrade - now we ARE NOT using SRCS as IDs of a message.
How you upgraded this installation?
Did you changed all files or just a single file?
Did you used files from -dist archive or from -dist-max archive?

OK, while the approach is definitely interesting i have one but :-)
<xmpp.sever.version>5.3.0-SNAPSHOT</xmpp.sever.version>
and if you browse <url>http://maven.tigase.org</url> you will notice that this repository is only for final/stable releases. All snapshot dependencies reside on our build machine hence propper setup of the repositories would be:
