Description of problem:
Vojtobox pops up (FE error box) when a snapshot is selected right after viewing Task.
Version-Release number of selected component (if applicable):
current master, commit f2d4194e5c
Steps to Reproduce:
1. Create a VM
2. Refresh webadmin page
3. Show VM detail
4. Select Snapshots tab
5. Click Tasks icon in upper right corner
6. Click Tasks icon again to close Tasks view
7. Select arbitrary row in snapshot list, e.g. "Active VM"
Vojtobox pops up, see attached ui.log
snapshot row selected
It ends up that VmSnapshotListModel's entityModel.entity becomes null when Tasks is opened and closed. VmSnapshotListViewItem line 202, listModel.getEntity() fails.
Alexander should be way more familiar with this code.
