Hibernate session's flushMode set to FlushMode.MANUAL unexpectedly

[olisikh]

Hi, guys.

Nice plugin, very useful, thank you for it!

I had taken a look at #15 issue, and was happy to see that some issues with hibernate sessions were resolved, but it seems not all of them.

I have elasticsearch-grails-plugin up-to-date taken from your repo. When I try to save any item to database and then to remove it via my "admin UI", an exception is thrown after calling delete operation. Here's the message:

  Message: Write operations are not allowed in read-only mode (FlushMode.MANUAL): 
  Turn your    Session into flushMode.COMMIT/AUTO or remove 'readOnly' 
  marker from transaction definition.

This error is thrown only when plugin is enabled. As a workaround, which prevents this weird exception:

  Domain.withTransaction {
      domain.delete(flush: true)
  }

But it's not pretty, is it? Appreciate any help! Is it a hibernate bug, or another plugin's session management bug?

this is a weird phenomena. I use a Filter to set each session.setFlushMode(FlushMode.AUTO).

or do sessin.flush in filter' afterView closure.
