java - Lazy loading in Hibernate -


My Java Web application uses Hibernate to ORM In some of my objects, I use lazy loading until then To get it until I need it. The problem is that I load the initial object in a session, and after that the session is destroyed when I try to resolve the lazy-loaded collection in my object later, then the following error Receives:

org.hibernate.LazyInitializationException: Failed to start a collection of role: common. Model.impl .User.groups, no session or session closed

I tried to add a new session with the archive and then tried to solve it, but it was a Only gives results.

Does anyone know how to solve lazy collection after the original session is over?

Thank you ...

three Option:

  1. call Hibernate.in initialize (..) whenever your archive will be disconnected from the current session

  2. Announce as the collection FetchType.EAGER

  3. .

    merge (..) your user object back in new session

I tried to use Expression trees, but they had a second thought for this moment on my head, where the lambda function was to be executed inside the statement such as: values ​​for matchingRows = matchingRows for each value Where (function (row) row.c...

asp.net mvc - Dynamically Generated Ajax.BeginForm -

I have a problem with ASP.NET MVC Ajax forms. I generate many Ajax form in a table such as: & Lt; Input type = "submit" name = "activity" value = "add activity" / & gt; & Lt;%}% & gt; & Lt; / TD & gt; & Lt; / TR & gt; & Lt;%}% & gt; So far so good. When I post one of those forms, it gives a partial view in a div, and in this new partial view a new Ajax Beginnform (which is not in Genesis form) This second Ajax Beginnorf is exactly like the ones I got on the table, but when I post it, I do not get the "Ajax Post", but a normal post that sends me to a new page, I do not know whether the two Ajax forms What is the reason for the difference between, why is it the "dynamically generated" Ajax form behaves like a normal HTML form? By the way, I know that I can do it in different ways using javascript, but I would like to understand whether it can only be done using MVC helplars and Ajax lib...
