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

[Sei Syvalta (JIRA)]

Sei Syvalta updated RF-4403:
----------------------------

    Description: 
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).
