Ilya Shaikovsky resolved RF-4403.
---------------------------------
Resolution: Done
modifiable model sample implemented at rf-demo
> 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
> Components: component-tables
> 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).
