[jbossseam-issues] [JBoss JIRA] Closed: (JBSEAM-129) JSF SelectItems automatic Converter creation using a @Selectable annotation

JSF SelectItems automatic Converter creation using a @Selectable annotation --------------------------------------------------------------------------- Key: JBSEAM-129 URL: http://jira.jboss.com/jira/browse/JBSEAM-129 Project: JBoss Seam Issue Type: Feature Request Components: JSF Environment: Jboss Application Server using Myfaces jsf and Seam from CVS Reporter: James Salt Assigned To: Pete Muir Original Estimate: 1 week Remaining Estimate: 1 week The entity class annotated with @Selectable would have to have an @Id attribute and a attribute annotated with something like @SelectionName for the displayed name of the object in the selectItems. The converters for each @Selectable entity could be created and cached at seam scanner time for each entity component that had @Selectable annotation. This scanner task would also need to dynamically register the converters with jsf/myfaces which I believe is possible using the myfaces Application class (don't know about the RI implementation). The user would be responsible for the creation of the list of objects (Seam supplying a static method to convert a list of objects to a list of select items), then the converters would deal with converting the selected item back to the object using a direct database lookup. As mentioned in the below thread, the object marked as @Selectable would need to implement a custom equals operation (being careful about @Datamodel update issues), so that myfaces could validate it correctly. For reverese engineering purposes, anything that has a field of a certain object would infer that that object is selectable, then the user could customise which field is used for the @Selectionname annotation. This would be very valuable when reverse engineering, and would remove a significant coding burden from the Seam developer.
