New content model definitions

andrepra — Wed, 17 May 2006 16:31:54 GMT

Following the procedure explained in the wiki for the creation of new content model xml I've configured the spring extension file terminating with -context.xml in the extensions directory. If I define two content models in two different files and I use two diffrent -context.xml files to load these e

No, you don't have to use a single -context.xml file to register models. Alfresco's own models are registered this way.

Having just scanned the function throwing the NPE, the cause is not obvious without some more context. Can you provide:

- the model definitions
- the context definitions which register the models
- the web client content-types definition
- the line number where the NPE is reported (should be in the exeption trace from the error page or the server console)

Thanks.

I can confirm that there is a problem when having multiple *-context.xml files.

Scenario: I'm using custom-model-context.xml for adding a custom aspect. Everything works well. After that I've created new xyz-context.xml and xyzModel.xml files, made the required changes to web-client-config-custom.xml. Restarted Alfresco and I can't see the new content types when accessing "Create Content Wizard". But when I try to create a custom rule and choose "Items of a specified type or sub-type", I get the following error:

if I stop Alfresco, rename/remove the custom-model-context.xml to custom-model-context.xml.sample and start Alfresco, I'm able to see the new content types defined in xyz-context.xml. I've created new items using xyz types and it worked.
