cannot update list data in the front site.

[quintenjiang.kinsonjob.yahoo.com]

Hi,

I define equals method in my entity bean like this:

public boolean equals(Object obj)

{
          if (!(obj instanceof Member)) return false;
          Member other = (Member) obj
          return other.getCellNumber() != null && other.getCellNumber().equals(this.getCellNumber());
}

in order to work at rich:orderingList; which it works well.
But it not work at the data table rich:dataTable; when I update some data, and re-load data list from server site, but it does not change at the front site.
of course if  I remove the equals method in the entity define, this rich:dataTable works well, but rich:orderingList did not work.

I am using seam working with richfaces

Some one can figure out what happened on this situation?





Thanks,
