Could not open Hibernate Session for transaction - when making service calls in Bootstrap.groovy

[berinle]

Apologies for double posting...

So I start a vanilla grails application, create an entity, a service with one method to save some instances of my entity and then in BootStrap.groovy, I call the service method.

I then added elasticsearch plugin.

Now when I invoke run-app, I get an error

Caused by CannotCreateTransactionException: Could not open Hibernate Session for transaction; nested exception is org.hibernate.SessionException: Session is closed!

which makes no sense, since services has a transaction wired in by default.

My domain: class Foo {

    String name 

static searchable = true 

static constraints = { 
} 

}

My service: class SimpleService {

def serviceMethod() { 
  10.times { 
  new Foo(name:'some-name-' + new Date()).save(flush:true) 
  } 

  println 'finished saving 10 foos' 
} 

}

Bootstrap: class BootStrap {

    def simpleService 

def init = { servletContext -> 
println 'calling service method' 
simpleService.serviceMethod() 
println 'ending call!' 
} 

def destroy = { 
} 

}

If I remove

static searchable = true

on the domain, the error goes away and things work as expected.

Can someone please shed some light on this?

Thanks.

PS: You can find the sample project @ https://github.com/berinle/grails-search-app, if you want something to test with or see the error in action.

Also: I posted on the grails user forum @ http://grails.1312388.n4.nabble.com/elastic-search-plugin-mysteries-td4366648.html

It seems there is an issue in Grails 2.0 with the bulk indexing on startup. Add

elasticSearch.bulkIndexOnStartup = false

in your Config.groovy for a workaround for now. I'll look into this issue asap.
