[richfaces-issues] [JBoss JIRA] Commented: (RF-4403) Better support for datatable sorting in DB

Better support for datatable sorting in DB ------------------------------------------ Key: RF-4403 URL: https://jira.jboss.org/jira/browse/RF-4403 Project: RichFaces Issue Type: Feature Request Affects Versions: 3.2.2 Reporter: Sei Syvalta Assignee: Ilya Shaikovsky Fix For: 3.3.1 Attachments: rf4403.zip Currently, there are two options for sorting data in dataTable (with or without paging): 1. use sortBy attribute in rich:column. The downside is that the whole data set needs to be loaded from DB for sorting. 2. use commandLinks in rich:cloumn. The downside is that you need to manage the icons, direction etc. by yourself (all this is managed by richfaces in case 1.) So what I would find very useful would be to get the sort property(ies) to a bean, where it could be used in sql "select ... order by sortProperty limit start maxResults..." clause. Some discussion about this is also in RF-2916. To conclude, I'm using a custom datamodel with dataTable pagination which loads data lazily and everything is working fine. However, I would like to add sorting to the headers of table, and I would like to do that at the database level, without doing all the ui logic manually (ie. option 2).
