Hello all,
we have multithreaded Content Aggregator which is based on the
CIncludeTransformer and it also implements CacheableProcessingComponent
for caching .. it used to work fine for cocoon 2.1.x but with cocoon 2.2
it gives strange error .. it is actually a generator and it gives error
in the generate method ..
the code where it gives error
// generate...
for (Part part : this.parts) {
if (this.manager.hasService(IncludeCacheManager.ROLE)) {
part.uri = this.cacheManager.load(part.uri,
this.cachingSession);
} else {
this.getLogger().error(
"The ContentAggregator: aggregator cannot
find the IncludeCacheManager");
}
}
// aggregate...
StreamPipe streamPipe = new StreamPipe(this.contentHandler);
for (Part part : this.parts) {
streamPipe.firstElement(part.element, this.rootElement,
part.stripRootElement);
try {
System.out.println("ParallelContentAgg.part.uri:" +
part.uri);
this.cacheManager.stream(part.uri,
this.cachingSession, streamPipe);
} finally {
streamPipe.lastElement(part.element);
}
}
it gives the following error
Caused by: org.springframework.beans.factory.BeanCreationException:
Error creating bean with name
'scopedTarget.org.apache.cocoon.el.objectmodel.ObjectModel': Scope
'request' is not active for the current thread; consider defining a
scoped proxy for this bean if you intend to refer to it from a
singleton; nested exception is java.lang.IllegalStateException: No
thread-bound request found: Are you referring to request attributes
outside of an actual web request? If you are actually operating within a
web request and still receive this message,your code is probably running
outside of DispatcherServlet/DispatcherPortlet: In this case, use
RequestContextListener or RequestContextFilter to expose the current
request.
