No Hibernate Session bound to thread

Hi everyone,

I installed Grails 1.2, created a demo app and installed the plugin grails-grailsflow-core-1.0-rc1 with dependencies (with activation and javamail which are not listed in the README.txt for installation).

When starting this new app (working before I installed the plugin) in development mode (hsqldb), I got the following exception :

2010-01-11 14:21:13,680 [main] ERROR context.ContextLoader  - Context initialization failed

So the line in error :

Am I missing something about Hibernate Session initialization ?

Same for me, with Grails 1.2 final version

It seems to be related to the Boostrap.

I commented the lines in method def doWithApplicationContext and migrated the
creation of FlowStatus entries to my application Boostrap and now the application starts.

But it crashes if I try to load a view. It seems that there's another issue with the GTag

Hi,

Same for me.

Grails 1.2.1 and doWithApplicationContext moved to Bootstrap.

Could somebody give a fix or workaround ?

Cheers.

We have made the changes for Grails 1.2. The nightly build is working with Grails 1.2 for the last couple of weeks.

I will doublecheck with Grails 1.2.2 before we do the final release of GrailsFlow 1.0.

Im getting this error with grails 1.3.5 and grailflow 1.0 release, has this issue been resolved? Any help figuring it out would greatly be appreciated
