Hi, I would like to know what is a status of the new feature Hibernate Custom Mapping. There is already some impl and tests in SVN but no documentation. Is the impl ready to try? If yes, any hints how to start? Thanks, Jiri.

Hi Jiri, The custom mapping feature is working.. There is a need for some documentation and I haven't added the fields in the class editor to edit them through the web. Currently custom mappings can be enabled programatically for example using plugins.. The best way to actually test the feature is to look at the test. Of course there are some limitations.. Currently enabling a custom mapping after already having data in the db is not a very good idea (there could be problems). Ludovic Jiri Luzny wrote:

Hi Ludovic, ..great, I will try it... For the enabling of custom mappings I would like to use the new import feature. However, I'm not sure if my assumption how the import works is correct: when importing any doc which has some objects assigned, it together with objects also automatically manages class definitions: if certain class definition doesn't exist it gets created and if it already exist it gets updated. Is it right? Or before importing any doc the corresponding class definition must already exist in its master doc? In this case how do you ensure the master doc with class definition is imported earlier than any other doc using this class? Thank you, Jiri. On Thu, 18 Aug 2005 17:42:56 +0200 (CEST), you wrote:

Hi Jiri, No, you have to import the class definition too. XWiki does not automatically manage class definition. Maybe it can be done in the futur. The update of a class is difficult, how to know if the user have modified the class, what doing in this case? What we do with objects which are using this class? I don't think the order for the import of class and objects are important. But Ludovic can you confirm?

This is indeed an issue.. The class does need to exist before so that the custom mapping is taken into account. We need to modify the import/export to save classes to the DB before any objects using these classes. Ludovic Jiri Luzny wrote:

Just for better understanding: if the class definition included in XML of every doc which has an object is not used for the class management, what is it used for? Thanks On Fri, 19 Aug 2005 10:54:18 +0200 (CEST), you wrote:

The reason I added the class definition is so that versioned documents include it so if you request an older version of a document, it has the classes at the time it was versioned.. This would be usefull to really evaluate a document and objects in the same context as at the time it was versioned.. Practically it's not really used.. We could get rid of it in the export and only keep it in the versioned xml.. Ludovic Jiri Luzny wrote:

New subject: [xwiki-dev] Status of Custom Mapping

Ludovic, I'm trying the custom mapping and I would like to discuss some issues I have figured out so far: - it doesn't seem that custom mapping is exported to class definition XML therefore cannot be imported e.g. from a backup - I guess custom mapping for StaticListClass and DBListClass is not supported now but due to IMO wrong conditional logic in XWikiHibernateStore.isValidColumnType() (should return false when validtypes is null) you can have a custom mapping for such classes as long as the class is not marked as MultiSelect (when setting MultiSelect I'm getting ClastCastException from Hibernate). I understand that implementation of full list class functionality when a List class set to RelationalStorage might be difficult, but it would be nice to have support at least for single field MultiSelect! - Can I mix custom mapping with the default one within one class?

yes.. fields that are not custom mapped are still read/written in the generic tables.. Now if the field is custom mapped in the future the result will be non predictable for the data stored in the generic tables.. Ludovic
