ScrollableDataTable. Autoscroll Problem. Selection-Problem.
-----------------------------------------------------------
Key: RF-5054
URL: https://jira.jboss.org/jira/browse/RF-5054
Project: RichFaces
Issue Type: Bug
Affects Versions: 3.3.0
Environment: Apache Tomcat 6.0.16 Server
Eclipse 3.3.2
Java 1.6
Windows XP SP3
RichFaces 3.3.0-20081124.104647-77
Reporter: Buttau Alexander
I have detected two problems concerning ScrollableDataTable.
I have created a Project that recreates these two problems. The project has
only one page.
The page has a ScrollableDataTable with page size 30 (attribute row="30") bound
to an array with 32 Items and a CommandButton that rerenders a Panel with a
ScrollableDataTable inside and shows the current selection with
'javascript:alert(...)'.
Problem 1: Autoscroll Problem
1. You scroll down to the bottom.
2. Now you scroll to the top
3. After rerendering the ScrollableDataTable by clicking on CommandButton, it
will automatically scroll down to the bottom after rendering.
Problem 2: Selection-Problem
Under some circumstances the selection of ScrollableDataTable gets corrupt.
Here is the Test-Case to recreate this Problem:
1. Call Page. No item selected
2. Now scroll to the bottom. (Row C-31 is shown)
3. Select an Item (for example C-25) and click on CommandLink "Selection"
4. The ScrollableDataTable is not properly rendered. No header is visible, and
all columns are shown on the place of the first column. Probably a bug too?
BUT IT IS NOT A PROBLEM YET.
5. Now F5 to reload a Page. The Table is rendered correct. But the Row C-27 has
selection (Row C-25 was selected)
6. If you select a row now and click CommandButton "Selection" it shows always
the wrong id. This id differs from really selected by 2. For example you select
30 => it shows 28.
Tested with Firefox 3 and Internet Explorer 7.
