Nick Belaevski resolved RF-3833.
--------------------------------
Resolution: Won't Fix
Assignee: Tsikhon Kuprevich (was: Nick Belaevski)
The value of pageSize is not preserved between requests thus coding newly-added items not
being decoded thus causing no actions. Make bean of session scope to make the code work
<a4j:support> does not rerender specified component for newly
added rows in a datatable
---------------------------------------------------------------------------------------
Key: RF-3833
URL: https://jira.jboss.org/jira/browse/RF-3833
Project: RichFaces
Issue Type: Bug
Affects Versions: 3.2.1
Environment: JBoss 4.2.2 / Seam 2.0.2 / RichFaces 3.2.1 / Facelets 1.1.14
Reporter: Tareq Nabeel
Assignee: Tsikhon Kuprevich
Fix For: 3.2.2
When page is loaded initially and page size is 2, clicking on table rows causes
<h:outputText id="myText"> to rerender correctly.
However, when page size is increased to 4, clicking on the added rows (3 and 4) does not
rerender "myText". Clicking on rows 1 and 2 still updates "myText"
correctly.
<a4j:log> output for good rows clicks:
Response content:
<body>
<span id="text">event 1</span>
<meta name="Ajax-Update-Ids" content="text" />
</body>
Message: Find <meta name='Ajax-Update-Ids' content='text'>
<a4j:log> output for bad rows clicks:
Response content:
<body> does not contain the information above but <head> section contains
<meta name="Ajax-Update-Ids" content="" />
Message: "no information in response about elements to replace"
