please submit an issue with sample attached.
I have opened issue RF8339 https://jira.jboss.org/jira/browse/RF-8339
After doing a bit more investigation while preparing the example page to reproduce the error I have found that the error only occurs if a stylesheet is specified in the header. For example:
<link rel="stylesheet" type="text/css" href="http://localhost:80/site/css/components.css" />
This has also been noted in the issue.
thanks for your efforts!
We are also encountering the issue when using rich:extendedDataTable in Richfaces 4.x - are there plans for fixing the issue ?
