Thierry Delprat updated NXP-4657:
---------------------------------

    Status: Open  (was: Triage)

> extends audit service to support adapters in EL expressions
> -----------------------------------------------------------
>
>                 Key: NXP-4657
>                 URL: http://jira.nuxeo.org/browse/NXP-4657
>             Project: Nuxeo Enterprise Platform
>          Issue Type: Improvement
>            Reporter: Eugen Ionica
>
> *issue : with current audit service can NOT log values resulted from 
> customized method calls
> Audit Service use EL expression to add extra information to be logged.
> For now there are 3 objects available in the context to be used in EL
> expressions:
> message - Document message describing the event
> source - Document from which the event is from
> principal - Identity of the event owner
> <extension point="extendedInfo" 
> target="org.nuxeo.ecm.platform.audit.service.NXAuditEventsService">
>     <extendedInfo expression="${source.myschema.myproperty}" key="extraInfo" 
> />
> </extension>
> But sometimes we need to implement some logic to produce the value that we 
> want to record
> in our case
> [...]
> if (doc.isProxy()) {
>   CoreSession session = CoreInstance.getInstance().getSession(sessionId);
>   DocumentModel tmp = session.getSourceDocument(doc.getRef());
>   originalDocUUID = session.getSourceDocument(tmp.getRef()).getId();
> }
> else {
>   originalDocUUID = doc.getId();
> }
> [...]
> * posbile solution
> added a new extension point to 
> org.nuxeo.ecm.platform.audit.service.NXAuditEventsService called "docAdapter"
> using this point will register an adapter for DocuementModel
> <extension point="doc" 
> target="org.nuxeo.ecm.platform.audit.service.NXAuditEventsService">
>     <adapter class="org.nuxeo.myadapter" name="myadapter" />
> </extension>
> class - is the qualified name of the class that will wrap the document model 
> specified by "source"
> name - is the name that will be used in EL
> then win "extendedInfo" will add
> <extension point="extendedInfo" 
> target="org.nuxeo.ecm.platform.audit.service.NXAuditEventsService">
>     <extendedInfo expression="${myadapter.originalDocUUID}" 
> key="original_doc_uuid" />
> </extension>
