I am using nhibernate in an open session per view approach where the session opens before the action method and closes right after. Using an AsyncController makes this model break because the controller performs data operations even when it has returned from the original XXXAsync method but it finds a null session while the HttpContext.Current is null as well. Is there any way to fix this issue?
View 1 RepliesI've been reading up on DDD a little bit, and I am confused how this would fit in when using an ORM like NHibernate. Right now I have a .NET MVC application with fairly "fat" controllers, and I'm trying to figure out how best to fix that. Moving this business logic into the model layer would be the best way to do this, but I am unsure how one would do that.
My application is set up so that NHibernate's session is managed by an HttpModule (gets session / transaction out of my way), which is used by repositories that return the entity objects (Think S#arp arch... turns out a really duplicated a lot of their functionality in this). These repositories are used by DataServices, which right now are just wrappers around the Repositories (one-to-one mapping between them, e.g. UserDataService takes a UserRepository, or actually a Repository). These DataServices right now only ensure that data annotations decorating the entity classes are checked when saving / updating.
In this way, my entities are really just data objects, but do not contain any real logic. While I could put some things in the entity classes (e.g. an "Approve" method), when that action needs to do something like sending an e-mail, or touching other non-related objects, or, for instance, checking to see if there are any users that have the same e-mail before approving, etc., then the entity would need access to other repositories, etc. Injecting these with an IoC wouldn't work with NHibernate, so you'd have to use a factory pattern I'm assuming to get these. I don't see how you would mock those in tests though......................
There are various ways to handle session timeouts, like "meta refreshes" javascript on load functions etc.
I would like something neat like: 5 minutes before timeout, warn the user...
I am also contemplating keeping the session open for as long as the browser is open(still need to figure out how to do it though... probably some iframe with refreshing).
How do you handle session timeouts, and what direction do you think i should go in?
I am getting the following error in an Asp.Net Castle ActiveRecord app when trying to update an object:
"a different object with the same identifier value was already associated with the session"
I've looked up and down my code to see where else the object might have been created but I'm not seeing it. This is baffling as I have the exact same code on another page that works fine on updates
Now I'm thinking of trying to see where this other object is in the Session and either kill it or find out how it got into the session. How can I find this object?
[Update]
Ok, I finally found where the object is being called. However, I would still like to know how to find objects in the session for future reference.
I have NHibernate sessions cached in the ASP.NET session.
I came across a situation where a user edited an object so it's in their first level cache in the ISession. Another user then edited the same object.
At this point User1 still sees their original version of their edits where as User2 sees the correct state of the object?
What is the correct way to handle this without manually calling session.Refresh(myObj) explicitly for every single object all the time?
I also have a 2nd level cache enabled. For NHibernate Long Session should I just disable the first level cache entirely?
Edit: Adding some more terminology to what I'm looking to achieve from 10.4.1. Long session with automatic versioning the end of this section concludes with
As the ISession is also the (mandatory) first-level cache and contains all loaded objects, we can propably use this strategy only for a few request/response cycles. This is indeed recommended, as the ISession will soon also have stale data.
I'm not sure what kind of documentation this is for it to include both probably and then immediately say the session will have stale data (which is what I'm seeing).
I have a button control where I retreive 2 strings with 2 URL like in the code below.
What I wonder how it is possible to do, is how to open up 1 browser window with 2 Session Tabs where 1 Tab is [URL]
How can this be possible to do from code behind (C#)?

I have a site that I am trying to extend how long a session stays open even though the user is inactive. I have this set in my web.config
<sessionState mode="InProc" timeout="720" />
And this is set it IIS
Time-out (in minutes):
720
But it is still timing out after like 15 minutes.
I am a bit confused on how ASP.NET session works with my site, when a user opens up the site in multiple browsers, and/or multiple tabs. I see that after logging in with IE, i can open a new tab and not have to log in, and that if I log out of one tab, the other one will redirect to login after I try to do something. I also notice that if I log in with IE, i still have to log in with FF. My question - are session data shared between all of these sessions?
View 3 RepliesI am opening a window with window.open and I am losing the server session. Is there a way to open a window with Javascript and use the same session? I need this working in IE 7 and higher. I am working with ASP.NET on the server side. The sever does not have a sessionless cookie state.
<sessionState mode="InProc" timeout="15" />
Im trying to make a solution like this [URL] Now the question is how do I filter the request, I only want to Open an ISession if the request is for an ASPNET MVC Action, not for *.gif, *.css etc. How should I handle this filtering?

View 1 RepliesI'm storing a token in a session variable. I launch a report that needs this token in a new ASPX page by using the javascript windows.open function. When this new page loads the HttpContext.Current.Session is null.I have gotten around this by passing the token in the query string but activity in this window needs to keep the session of the parent window active and I'm not sure what the session object being null means for this scenario.

how to grid view open a popup using jquery (For saving & Updating)
View 2 RepliesI've inherited some code (not mine- I swear!) which uses a session variable in the header of the HTML to determine which javascript file to link to.i.e.
<SCRIPT language="javascript" src="../JavaScript/<%=Session("jsFileName")%>.js"></SCRIPT>
It does work, except that it won't let me change to design view. It gives the message
"Could not open in design view. Quote Values differently inside a '<%... "value" ...%>' block."
Anyone got any suggestions as to a workaround, that doesn't involve a huge rewrite.

View 1 Replieswe have a asp.net webforms app using NHibernate. Here are some specifics:We need Distributed Transactions because we write to the database as well as to a queue.Because this is a web app, we use the recomended Session-in-view pattern. We have a HTTPModule that opens the NHibernate session on the BeginRequest event and closes it on EndRequest.Within the flow of a request, we have several separate moments where we need to do transactional work. For this, we use TransactionScope.So basically, what happens is this (pseudocode):
using(var session = sessionFactory.CreateSession()){
using(var tx1 = new TransactionScope(){
