I've upgraded an ASP.Net Web application to the latest build of Fluent NHibernate (1.0.0.636) and the newest version of NHibernate (v2.1.2.4000). I've checked a couple of times that the application is running in Full trust. But I keep getting the following error:
Security Exception
Description: The application attempted to perform an operation not allowed by the security policy. To grant this application the required permission please contact your system administrator or change the application's trust level in the configuration file.
Exception Details: System.Security.SecurityException: Request for the permission of type 'System.Security.Permissions.ReflectionPermission, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.
Source Error:
An unhandled exception was generated during the execution of the current web request. Information regarding the origin and location of the exception can be identified using the exception stack trace below.
Anyone had a similar error? I've seach the web / stackoverflow / NHibernate forums but only found people who had a problem when running in medium trust mode, not full trust. I've been developing for several months on this application on this machine with previous versions of Fluent NHibernate and NHibernate.
The machine I'm running this on is 64-bit, you never know that this is relevant.
am trying to implement fluent nhibernate in MVC project...there were no build errors... but when i run the project i get this exception
System.Xml.Schema.XmlSchemaValidationException: The element 'class' in namespace 'urn:nhibernate-mapping-2.2' has incomplete content. List of possible elements expected: 'meta, subselect, cache, synchronize, comment, tuplizer, id, composite-id' in namespace 'urn:nhibernate-mapping-2.2'.
have no idea what am doing wrong here... the following is the code for opening session factory...
, I want to use fluent hibernate with asp.net but couldn't find any website or tutorial for that , they're all to configure it with asp.net mvc , anyone knows any?
I have a session criteria statement (Fluent NHibernate) that does not seem to filter the child collection even though I have Expressions/Restrictions defined.
This returns all the objects of type MyClass that have MyCollection.Property = value, however MyCollection is not filtered to MyCollection.Property = value
We are developing a multi-language web application with ASP.NET MVC 2 and Fluent NHibernate.Our platform will be multi-language. But just static text will be multi-language. Groups pages depends on community content whatever they use. Like Facebook.We decide to keep all language string in database. And load language when application starts.
I have the following models & mappings (code snippets further below).
One Competition has to have multiple CompetitionAnswers associated with it (multiple choice) from the outset.
At present, using the Fluent NHibernate mappings shown below, when I create a brand new Competition object, populate the properties, then create 3 brand new CompetitionAnswer objects and add them to the CompetitionAnswers property (property on Competition), I would expect to call Save on the session which would INSERT the 1 Competition row and 3 CompetitionAnswer rows to the DB.
However, as soon as I try to call Save on the session, it complains that CompetitionId is null and it can't insert a null into the CompetitionAnswers table for that field - which is right, it shouldn't, however, I assumed that the NHibernate would first create the Competition, then use the newly generated IDENTITY value (CompetitionId) in the CompetitionAnswers table?
I am using the above combo in a new web app Im doing just to try to learn to build new stuff to expand my knowledge. Im hoping to go live if I do a good job.. Im kind of new at MVC and the other products so I was trying to find a link to a good tutorial that set all of these up together.
I'm working on a RoleProvider in .NET, using Fluent NHibernate to map tables in an Oracle 9.2 database.
The problem is that the many-to-many table connecting users and roles uses a primary key generated from a sequence, as opposed to a composite key. I can't really change this, because I'm writing it to be implemented in a larger existing system.
Here is my UserMap:
public UserMap() { this.Table("USR");[code].....
Yet, this is giving me the error:
Type 'FluentNHibernate.Cfg.FluentConfigurationException' in assembly 'FluentNHibernate, Version=1.0.0.593, Culture=neutral, PublicKeyToken=8aa435e3cb308880' is not marked as serializable.
Is there a simple fix to allow this HasMayToMany to use my PersistentObjectMap extension? I'm thinking I may have to add a convention for this many-to-many relationship, but I don't know where to start with that, since I've just started using NHibernate and Fluent NHibernate only recently.
EDIT: I think I've found a possible solution here: http://marekblotny.blogspot.com/2009/02/fluent-nhbernate-and-collections.html
I'll try the above method of creating an entity and a class map for the linking table and post my findings.
EDIT 2: I created a linking entity as mentioned in the above blog post and downloaded the newest binaries (1.0.0.623). This helped me discover that the issue was with setting lazy load and trying to add roles to the user object in a completely new session.
I modified the code to move OpenSession to the BeginRequest of an HttpModule as described here. After doing this, I changed my data access code from wrapping the open session in a using statement, which closes the session when it is finished, to getting the current session and wrapping only the transaction in a using statement.
This seems to have resolved the bulk of my issue, but I am now getting an error that says "Could not insert collection" into the USR_ROLE table. And I'm wondering if the above code should work with a UserRoleMap described as:
public UserRoleMap() { this.Table("USR_ROLE"); [code]....
Hibernate's documentation for many-to-many relationship suggests creating an object to maintain a one-to-many/many-to-one, as in an ERD. I'm sure this would be much easier with conventional naming standards, but I have to stick with certain abbreviations and odd (and not always properly-implemented) conventions.

I am writing unit tests for fluent Nhibernate, when I run the test in isloation it passes, but when I run multiple tests. or run the test more than once it starts failing with the message below System.ApplicationException : For property 'Id' expected '1' of type 'System.Int32' but got '2' of type 'System.Int32'
How should one handle the situation where you may need to filter by a group of users.
Here is the scenario.
I have an administrator role in my company. I should be able to see all the data belonging to me plus all the other users who I have control over.
A plain old user however should only be able to access their own data.
If you are writing regular sql statements then you can have a security table with every user and who they have access too but i'm not sure how to handle this situation in the OO and ORM world.
Any one dealt with this scenario in a web application using an ORM?

I am trying to implement the Ajax HtmlEditor into my application. I currently am using a regular TextBox to load and save some data to some EMail template files and had to do some work-arounds to get it to accept the HTML Input. I am trying to upgrade it to use the Editor, but as soon as I insert the Editor and do a PostBack, I receive the Security Exception below. There is absolutely no change to the code-behind, so I don't understand the issue. There is so little on Google for the Version 3.5 Editor that I'm stumped. I have Debugging enabled, but it won't give me the Soruce Error either.

I'm getting this exception randomly in one webservice, it used to happen in the first call only, and in the second calls and so on it works fine ... and after a while without use the webservice it happens again. It seems to be that when the AppDomain is not loaded, the first time fails... and subsequent calls are ok; when IIS shutdown the AppDomain... the next call will fail again.
