>             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

> 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"
