Thanks for the bug report @kruge002 !

I was able to reproduce this and I suspect it is a UI issue.

This is the error on upstream/master:

[----] F, [2017-01-19T11:27:07.810357 #32231:2ad497fc0ae4] FATAL -- : Error caught: [ActionView::Template::Error] Couldn't find Snapshot with 'id'=2
/var/lib/gems/2.3.0/gems/activerecord-5.0.1/lib/active_record/core.rb:173:in `find'
/home/agrare/.bundle/ruby/2.3.0/manageiq-ui-classic-90608b7beb94/app/views/vm_common/_snapshots_desc.html.haml:5:in `__home_agrare__bundle_ruby_______manageiq_ui_classic______b_beb___app_views_vm_common__snapsho
/var/lib/gems/2.3.0/gems/actionview-5.0.1/lib/action_view/template.rb:159:in `block in render'

If we look at https://github.com/ManageIQ/manageiq-ui-classic/blob/master/app/views/vm_common/_snapshots_desc.html.haml#L5

It is trying to find the previous snapshot that you had selected: selected_id = Snapshot.find(session[:snap_selected]) but the snapshot that you had selected is now removed from the db.

Assigning to the UI team.

@ZitaNemeckova please take a look when you get a chance. I don't think we need a BZ as it's an edge condition that has a workaround (page refresh). Thx, Dan

[kruge002]

A page refresh is no workaround in this case. You have to logout and login again so "solve" the issue.

@dclarizio I have problem with deleting snapshot. Delete is initialized but never finished. If I delete it in code it deletes its children.

Solved #183 .
