Removing #content message send in EpUnifiedBrowserPresenter>>refreshIfMonitorLogSelected appears to resolve the issue.

Hi,

I'll take a look as soon as I'll have time.

My guess is that it is caused by the migration to Spec 2. Probably a presenter was returning a wrapped entity somewhere while Spec 2 return the entity directly. (Is just a guess ;) )

Hi @jecisc ,

The commit you made looks correct, but there doesn't appear to be a PR associated with it.

Thanks,
Alistair
