[ http://issues.apache.org/jira/browse/TAPESTRY-730?page=comments#action_12427481 ] A.J. commented on TAPESTRY-730: -------------------------------
BEA report it as corrected in 8.1 SP6 (http://edocs.bea.com/wls/docs81/notes/resolved_sp06.html#1864954) but I haven't checked it yet. CR259956 : "... Attempt to change the Content-Type after calling getWriter() threw an IllegalStateException. This exception no longer occurs. However, the new content type is ignored and the response is written back to the client with the original content type." cheers, Ozeebee > Cannot change charset from 'UTF8' to 'UTF-8 during
