[richfaces-issues] [JBoss JIRA] Commented: (RF-4317) scrollableDataTable: incorrect rows order after scrolling and other drawbacks

[Oliver P??tter (JIRA)]

    [ https://jira.jboss.org/jira/browse/RF-4317?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12427237#action_12427237 ] 

Oliver P??tter commented on RF-4317:
------------------------------------

Konstantin,

the description of RF-4178 is very thin. You are right, that the selection is not rendered correctly, when selecting an item and scrolling up and down. But this is not the main problem.

Please try again. I attached some screenshots

1) Load the page (screen0.png)
2) Select item2: The output shows item2 (screen1.png)
3) Scroll down to the end of the table (screen3.png)
4) Select Item25: The output shows item5 (screen4.png)

Please know, that the behaviour may differ, because this bug is a little indeterministic.

If you trace the selection listener in the controller bean, you will see that the row key is computed wrong.

We use these tables to maintain masterdata of our application. The user selects an item and can view or edit details of this item. So if the item which the user selects is not the item the user will actually edit we have a blocker. I think many other users use this functionality.


Hope this helps. 

Kind regards

Oliver

> When using a rather large number of rows 
> (for examle <input id="j_id1:articleList_rows_input" name="_rows_input" type="hidden" value="163586" />, but rows="30")
> scrolling for a while in a scrollableDataTable with IE6 or IE7 breaks the data that is shown in the table.
> The testdata that is shown in the table has an ascending row number without gaps in the data.
> After scrolling for a while the row numbers of rows that are visible
> in the table are not ascending anymore, there can be several blocks
> of ascending rows.
> If the table is in such a state then the data in the visible row does not
> correspond to the data of the selected rows.
