Hi
Thanks for showing this.
But can you please put everything together in a .zip or project on github
that is easy to run and reproduce what you do.
And create a JIRA where you can attach the zip or link to the github place.
Otherwise we dont have time to put all that together ourselves all the time.
This will make it much easier for everybody and a chance that this will be
looked into and resolved.
