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
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 sorting logic manually (ie. option 2).
