self-written DataModel as @DataModel for true pagination

[juergen.hartler]

Dear Seam-Team!

I have self-written DataModel extending the org.richfaces.model.ExtendedTableDataModel to support true pagination via the database. The only problem is just that the @DataModel tag of seam does not support self-written DataModels. I added manually in the downloaded source code of jboss-seam-2.0.2.SP1 and added to the class org.jboss.seam.faces.DataModels.getDataModel(Object value) the lines:

...

      else if (value instanceof DataModel){
        return (DataModel)value;
      }else{ ...

Could you please mind to add this to your next release?

Many thanks,
Juergen

For these sorts of requests, you probably should submit a Jira feature request.

In the meantime, you might look into using the DataBinder mechanism, which is how @DataModel is implemented.  Potentially just create your own new annotation, copy/paste org.jboss.seam.databinding.DataModelBinder, and tweak a few things.

Dear Matt!

Yes you are right an JIRA request would be better:

https://jira.jboss.org/jira/browse/JBSEAM-3608

To implement an own annotation instead of the @DataModel was my first intention as well, but I was not really sure if it is correct what I am doing and then I did not follow up this possibility.

I think it is not a problem for me to wait until it is added in a newer release of seam since I can meanwhile live quite well with my self-compiled code of seam-2.0.2.SP1.

Many thanks for your help and your quick reply,
Juergen

It's very easy fix, and we wait half a year for it... Is there any problem with it?

Any comment from Seam team...?
