Here's a starter list:
if hbm is hand generated, is it an embedded resource?
if using FNH, does it pass a PerssistenceSpecification test?
if not using FNH, can you save and then load the persisted class?
use Ayende's "sanity checks"
I'm sure many of you have gotten this one at one point or another. But have you ever gotten it when you knew your mapping was set up correctly?
I started getting this exception after I started using a new repository design, but only in one scenario! PersistenceSpecification tests pass, as do all repository methods (using SQLite).
The scenario that leads to the exception is when legacy projects from a different db are converted to green field system. The legacy system is from a different database and has it's own session factory, which should be irrelevant because the error comes after previously unconverted Projects are retrieved and in memory.
As the routine tries to save these unconverted Projects into the new database, the exception is thrown, full stack trace below.
Any ideas on how to build up the trouble shooting check list and solves this problem?
Cheers,

The problem here turned out to be that I was inadvertently binding the same session context to both the legacy and greenfield db session factories, first to the greenfield and then the legacy.

We are experimenting with Apache Ignite to use it as a Read and Write through caching layer for Distributed applications. The need is to weave a cache layer for the aggregates we depend on. Indiviual constituent entities that these aggregates comprise of, are managed entities maintained by EntityManager.
Two Questions:
Does Apache Ignite participate in Container Managed Transaction out of box ?
In order to understand solution to Q1 , I did a small experiment described below. Any insights on what induces below behaviour ?
Aggregates : Strategy and Strategy Parameter - one to many mapping.
Individual Entities : Strategy and StrategyParam (both managed by JPA/Hibernate).
CacheStore definition based on entitymanager : eg write method:
#Override
public void write(Cache.Entry<? extends Long, ? extends StrategyAggregate> entry) throws CacheWriterException {
em.merge(entry.getValue().getStrategy());
entry.getValue().getStrategyParamList().forEach(strategyParam -> em.merge(strategyParam));
}
Now when we init first node with above cache definition, I see the transaction nature working alright i.e. post method completion I see both cache and database updated i.e. I can read the changes from cache.
But as soon as second node joins the cluster, the same api throws up error
"no entitymanager available ..." followed by stacktrace having transaction has been rolled back. Though Read from both cache and direct read from entity manager works fine.
Stacktrace

I have been having an issue where Indexes for Search have been failing for a while it seemed like new indexes weren't getting created. I went to rebuild the Search index using that rebuild button, and all the documents that were previously indexed were no longer indexed.
I followed this article without results: Orchard - Search & Indexing issue
This did not work. I think probably because
App_data\Sites\Default\Search.settings.xml
doesn't get generated in the first place. I do however see a file:
App_data\Sites\Default\Search.settings.xml.lock
I believe the Orchard.Indexing.Services.IndexingTaskExecutor UpdateIndexBatch method is failing because my impression is the lock file would be created and then deleted if it was working. Here is a possibly relevant error:

Another error I see that I believe is related to the issue seems to occur in Orchard.Indexing.Handlers.InfosetFieldIndexingHandler

To note, I did try to generate a new index and just have it index news articles. This did not work, or generate the settings.xml file either.
Is there a database location that I should be looking at that could be containing null dates, or should I be looking elsewhere? Any help would be greatly appreciated.
Edit: It has been two days and no responses, so I made a post with updated details on git (in case someone is looking for an answer to the same question, and in case git hub has an answer git hub issue)
The solution was found. There was some null data within ContentItemRecord. The null Data and ContentType_id resulted in no indexes being built even unrelated index.
Here is the query we used to find the bad data. The xxxxxx would need to be replaced by whatever prefix is associated with your table, but gives you an idea what to do.
SELECT *
FROM [dbo].[xxxxxx_Orchard_Framework_ContentItemVersionRecord] civr
LEFT JOIN [dbo].[xxxxxx_Orchard_Framework_ContentItemRecord] cir ON civr.ContentItemRecord_id = cir.Id
LEFT JOIN [dbo].[xxxxxx_Orchard_Framework_ContentTypeRecord] ctr ON cir.ContentType_id = ctr.Id
WHERE cir.Id IS NULL OR cir.Data IS NULL OR ctr.Id IS NULL

I've never used RavenDb it looks interesting but I'm falling at the first hurdle.
I've downloaded, unzipped and I run C:\RavenDB\Server\Raven.Server.exe
and it flashes up and disappears.
I tried running from a dos prompt and I got this exception:

I'm working against the FNH trunk and NH 2.0.1. Funny thing is I am
able to compile my mappings (via AutoPersistenceModel.CompileMappings)
and write them to the file system successfully - FNH doesn't complain.
It is only when attempting to build the session factory that
everything goes kaboom with the not very helpful error message above.
Anyone got any ideas?
I found that the inner exception gave more details. In my case I had to add the NHibernate.ByteCode.Castle.dll file to the references.
Fluent NHibernate itself rarely complains at you directly. Internally it's just building up your HBM files for you so if you told it to build something wrong then NHibernate proper will get grumpy.
If you're not already, you might want to start with exporting your mapping files like so:
.Mappings(m => m.FluentMappings.AddFromAssemblyOf<MyClass>()
.ExportTo("path")
Then you can dig around in there to see if something is wrong. I do recall getting this error once before and I think it relates to a mismatch in the number of columns mapped. It was one of those easy-to-miss errors in my mapping, so unfortunately all I can suggest is to really scour the output of ExportTo for anything that doesn't make sense.
We'll need to see your Configuration to help much. But this part of the stack trace should give you an idea of where to start.
