------------------------------------
Status: Patch Available (was: Open)
> The Status of DataTable wasn't saved when use HashMap to reserve DataSource.
> -----------------------------------------------------------------------------
>
> 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.
