Eduardo,

i was trying to figure out, why in your installation it checks for the table name "APM_PARAMETERS" while on my installations, it checks for "apm_parameters". Fixing one symptom does not help much, since you will run into similar problems later on.

Since xotcl-core uses the table name from acs_object_types for the parameter class, i am wondering, what the following query returns on your system:

select object_type, table_name from acs_object_types where object_type = 'apm_parameter';

I've never had any trouble using XoWiki in this version, and in my little understanding about the package, I couldn't see any change in the ACS-Core that would afect it.

The versions of xotcl-core in cvs head has a much wider support of the acs-type system (see e.g. http://www.openacs.org/forums/message-view?message_id=1165841)
and is much tighter integrated with it. the according xowiki versions use these features. There are changes in this regard in acs-core, see e.g. http://www.openacs.org/forums/message-view?message_id=1201818 for some consequences.

unlike most other packages, the xo* packages tried in the past to work as good a possible with about all kind of openacs installations. Therefore, there are already many
package dependencies included. Try the following for a better understanding of the dependencies:

fgrep -R "ad_acs_version" packages/xo*

As said before, the head development is based on 5.3 and cvs head. Providing 5.2 support is probably not hard, but currently, i have no time to work on that.

btw, you did not state, what version of XOTcl you are using (grep for XOTcl in your error log).

Hi Gustaf,

I'm starting to think you are right about the compatibility problem. Maybe the new version of XoTCL can not be used in ACS-Core 5.2.3. The query you've mentioned returned the APM_PARAMETERS indeed. It has something to do with this diff:

http://cvs.openacs.org/cvs/openacs-4/packages/acs-kernel/sql/postgresql/apm-create.sql?r1=1.66.2.1&r2=1.61.2.3

It seems like the data model changed a lot between the oacs-5-2 and the oacs-5-3, wich makes me think a version upgrade will be needed in order to make XoTCL and XoWiki work appropriately. I could work in some changes to provide oacs-5-2 compatibility, but I don't know if it's worth. My upgrade fear is allways related to the compatibility of my systems, assuming all the changes I've done myself, but I guess there's no other way.

At least I can say the XoTCL 0.56.3 and XoWiki 0.60 are compatible with oacs-5-2. Thank you very much for all your help.
