Description

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.
