问题 I would like the rule for which "Persist activities cannot be contained within no persistence blocks" error happens in WF4. I see that you can not persist between the first receive-send, but I do not understand the general idea. Any comment? Thanks 回答1: The goal of a no persist zone it to indicate that you are doing something that can't be resumed from the middle of it. For example a Receive and SendReply action, if you persist in the middle you can also resume from there if the workflow

问题 I know this has been asked a lot of times before, I know it because I've searched for every related question to my problem to try to find a solution, however, none of the proposed solutions are working for me and I'm pretty sure that I have to be missing something. Person Class: @Entity @Table(name = "person", schema = "test") public class PersonEntity { @Id @Column(name = "id") private long id; @Basic @Column(name = "name") private String name; @Basic @Column(name = "age") private int age;

In a Transactional function, calling clear() detach all entities?

由 末鹿安然 提交于 2019-12-11 02:41:48
问题 I am using Hibernate as JPA provider and in a function, I am creating an instance of different entities. Once I call clear() for one entity, I can't persist() the other entities. My code is pretty more complicated, and at a point I am obliged to call flush() and clear() for one type of entities (and NOT for the other types) in order to free some memory. A simplification of my code is as follow: @Transactional void function() { EntityType1 entity1 = new EntityType1(); EntityType2 entity2 = new

Detecting page unload in angularjs

由 别来无恙 提交于 2019-12-10 12:58:44
问题 I have a javascript object which I need global to my angularjs application. When the application is about to be unloaded (due to a page refresh or some other scenario), I would like to persist the object to browser storage. I believe adding the object to $rootScope would fulfill the first requirement of making the object global, but writing the object to storage during the onbeforeunload event, would require access to the $rootScope variable. Is it possible to detect a page unload event in
