Specified Method Not Supported

[Arman]

With Nhibernate 3.3.1.4000 and Fluent Nhibernate 1.3 , use code like this :

        var query = from Person person in Session.Query<Person> select person;

        var query2 = from Person person in query select person;

you will get "Specified Method not supported" Exception. BUT if you change them to this, it works :

        var query = from person in Session.Query<Person> select person;

        var query2 = from person in query select person;

i mean if you specify the class type in linq query on query variable , Nhibernate cannot run the query, but if you remove it's type, it can be run.

[Arman]

is there anybody who can help me ?

I don't really understand your problem. You query for Person and then again for person. 

Aren't you just forgetting the round brackets after Query<Person> ?

Why do you need to specify the type? Isn't the result typed by default?

This is not a real case.

this is just my way to show you what the problem is.

The problem is lay down under specifying Linq Variable type in Linq query.

I'm not sure I understand.

All linq variables are already strongly typed.  There is no need to declare from Person person, because the compiler is taking the type from your Session.Query<Person>.  it knows you are querying a strongly typed list of Persons so the type of person must be Person.

Yeah, thats correct.

so if i explicitly state the variable type, it should not be any problem. but it is a problem.

somebody should check this case with nhibernate sourcecode or state a bug for them to chechk it.

You can report it here:
https://nhibernate.jira.com/browse/NH

Please include full exception details and a test case. See http://nhforge.org/blogs/nhibernate/archive/2008/10/04/the-best-way-to-solve-nhibernate-bugs-submit-good-unit-test.aspx for help with that. You can also fork NHibernate on github, create a branch for the issue and submit a pull request with the test case.

Hi,

It should be fixed with latest trunk already. 

You could download latest version here: http://teamcity.codebetter.com/viewLog.html?buildTypeId=bt7&buildId=lastSuccessful&tab=artifacts
