hi Thanks for your reply.
I started debugging the code and found some pointers but not able to fully
identify the root cause.
What I found is,
In TilesRequestProcessor class
protected void doForward(
String uri,
HttpServletRequest request,
HttpServletResponse response)
throws IOException, ServletException {
if (response.isCommitted()) {
this.doInclude(uri, request, response);
} else {
super.doForward(uri, request, response);
}
}
with version 7.0.39, somewhere
org.apache.jasper.runtime.ServletResponseWrapperInclude.*isCommited* is
setting to false, causing forward but response is already commited and
throws IO Exception.
with version 7.0.37, particularly for this request this flag sets to true
and it works.
any pointers on this ? how can I find from where this is setting to false ?
