don't allow method invokes on core session without a transaction

When application is invoking a core session without a transaction active, the system is warning you with the following message : "Session invoked in a container without a transaction active" If the warn occurs in the processing of a web request, that means that you've forgot to configure the request controller for injecting the transactional context. Looks at the following snip-set that show you how contributing to the request controller for this. <extension target="org.nuxeo.ecm.platform.web.common.requestcontroller.service.RequestControllerService" point="filterConfig"> <filterConfig name="MyFilterConfig" transactional="true"> <pattern>${org.nuxeo.ecm.contextPath}/<my-pattern></pattern> </filterConfig> </extension> In the other cases, you should manage the transaction demarcation in your own code. Here is a snip-set that can help you for doing this job. TransactionHelper.startTransaction(); try { .... } catch (Throwable e) { TransactionHelper.setTransactionRollbackOnly(); } finally { TransactionHelper.commitOrRollbackTransaction(); }
