-----------------------------------------------------------------------------

                 Key: TOMAHAWK-1352
                 URL: https://issues.apache.org/jira/browse/TOMAHAWK-1352
             Project: MyFaces Tomahawk
          Issue Type: Bug
         Environment: tomahawk  1.1.7
myfaces-core-1.1.6
            Reporter: Tang Yongkang


I'm using  a HashMap to reserve the form values.
The search result  is a type of ArrayList. It is needed to edit the search 
result and then save them to database and redisplay the datatable.
But  when redisplay the datatable,  I found that the Status was not saved. It 
only dispaly ONE ROW in the datatable.

I trace the source and found the following source in AbstractHtmlDataTable.java:
// Method Name: updateModelFromPreservedDataModel

517                if (lst!= null && lst.size() > 0)
518                {
519                    vb.setValue(context, lst.get(0));
520                }

At the  row 519, the ArrayList was constrained to ONE RECORD Array.

I changed the source as following, and it works fine.

517                if (lst!= null && lst.size() > 0)
518                {
519                    vb.setValue(context, lst);
520                }

I don't know why it was restraned to one record array,
But perhaps reduce the restrains may make myfaces more flexible.

thanks a lot in advance.
