feature.

LDEV-5144 Extract AE tab management to TBL monitoring

Not every AE tab will be an Assessment, so we need tabs to be

LDEV-5162 Fix Ordering answers saving to DB

To reflect an order that a learner put his answers, a TreeSet was used.

Its comparing function uses displayOrder.

It works fine when elements are put into the set during the first save,

i.e. the first autosave or a submit before the first autosave.

But when another save occurs (another autosave or a submit after the

first autosave), the set of answers is not recreated. Only displayOrder

of answers is modified. But TreeSet is not aware of it and keeps old

ordering. The iteration that happens during the save picks up answers in

the old order.

The fix uses real displayOrder value instead of counting on correct

order in TreeSet.

Another solution would be to rebuild the set after modifying answers'

displayOrder.

LDEV-5025, LDEV-5120 Softly remove duplicate rating criteria

For Assessment and Dokumaran we only allow one rating criterion each. On

high load, after a gate was opened, there is a chance that 2 learners

will detect no criteria and both will create one, resulting a duplicate

criterion. Instead of throwing a hard exception and rendering the

activity unusable, just remove the duplicate criterion ignoring any

exceptions. This is lighter than having a multi-node synchronization.

LDEV-4944 Recalculate marks only for learners with matching VSA answer

Recalculating all results bound to a given QB question is an enormous

job. We need to focus on results that actually changed.

LDEV-4944 Synchronise VSA answer allocation

We need to synchronise this operation.

When multiple requests are made to modify the same option, for example

to add a VSA answer, we have a case of dirty reads. One answer gets

added, but while DB is still flushing, another answer reads the option

without the first answer, because it is not there yet.

The second answer gets added, but the first one gets lost.

We can not synchronise the method in service as the "dirty" transaction

is already started before synchronisation kicks in.

We do it in MonitoringController, before transaction starts.

It will not work for distributed environment, though.

If teachers allocate answers on different LAMS servers, we can still get

the same problem. We will need a more sophisticated solution then.
