[jbossseam-issues] [JBoss JIRA] Created: (JBSEAM-1895) Allow @DataModelSelection annotation to be used without accompanying @DataModel annotation

Allow @DataModelSelection annotation to be used without accompanying @DataModel annotation ------------------------------------------------------------------------------------------ Key: JBSEAM-1895 URL: http://jira.jboss.com/jira/browse/JBSEAM-1895 Project: JBoss Seam Issue Type: Feature Request Environment: CVS based Seam Reporter: Wolfgang Schwendt Priority: Optional At present a @DataModelSelection annotation (and similarly @DataModelSelectionIndex) can ONLY be used in a component when there is also an accompanying @DataModel annotation placed on a field or getter method of the same component. The method getDataModelSelectionName() of org.jboss.seam.Component enforces this requirement. However, it would be very useful if the @DataModelSelection annotation could also be used in a component which doesn't expose a DataModel via @DataModel. It would allow the programmer to handle a data model selection in a different backing bean than the backing bean which exposed the DataModel, or put in other words, separate the data model generation from the selection event handling. If there are conceptual reasons against doing this, please document them in the Seam documentation. Workaround at present: Rather than using @DataModelSelection, inject the DataModel with "@In" into the component that should process the selection and get access to the selected row and selectionIndex via the injected DataModel. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.jboss.com/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
