task #3722
closedUsing @OrderColumn does not work in trees
100%
Description
For TaxonNode trees and feature node trees we tried do use @OrderColumn annotation for automated sortindex. However this doesn't seem to work in the selfreferencing evironment of a node. Maybe the fact that null values must be allowed for the root node is one reason for it.
@OrderColumn work for Classification.rootNodes.
This seems to be fixed since hibernate 4.1.11/4.2.0. We still use 4.1.10. So maybe an upgrade is enough.

@IndexColumn does not work because not every FeatureNode has a parent. But only NotNull will solve the problem (otherwise we will need a join table

reading works, but writing doesn't
The reason why the automated version is better is that we need some additional when adding, removing etc. nodes (e.g. in addChild(child, index) which is not nice. However it is not critical as it works the way it is implemented now.

Probably solved, still needs intensive testing and code cleanup.

For polytomouskey nodes there are still null values, after creating a new alternativ and saving the rootnode contains three null values at the beginning of the array.

Did you also test for TaxonNodes? PolytomousKeyNodes maybe still need cleanup. I cleanup TaxonNodes already and tested a bit with TaxEditor and did not get any errors. But we definetely need more testing and also debugging like you did to verify no null values exist.
Which data did you test?

Yes TaxonNodes work as expected, I tested creation of a new node, moving and deleting a node.
I tested with local copy of caryophyllales_spp

SQL for testing persisted Polytomous Key Nodes:
SELECT pkn.id, pkn.created, nodenumber, KEY_id, parent_id, sortindex
FROM PolytomousKeyNode pkn
ORDER BY key_id, parent_id, sortindex

Term trees/nodes also seem to work. Katja, can you please double check this?

I tested term trees with moving nodes, creating new nodes and deleting nodes and everything works as expected.

On PolytomousKeys:
- added a fresh PK
- added a new top level node (like always) results in a sortindex 1 for this node but should be 0
- reverting this to 0 in DB, loading the key again, adding an alternative and save results in sortindexes 2 and 3 for the resulting 2 alternatives
- reverting this again to 0 and 1 in DB, loading the key, adding a further alternative and save results in sortindexes 3, 4 and 5 for the resulting 3 alternatives.
- only changing the statement for the 3rd alternative and saving again result in the following exception which seems to show that the data already has the null values in the list. Is this because the save/merge result is merged into the session or is there something wrong in the node handling it self on taxeditor side?

This ticket is more about @OrderColumn generally does not work which is not the case. The remaining issue is a NULL-Value issue related to #5536 which is more or less independent of the @OrderColumn itself. We removed the workaround created for #5536 as we hoped that the issue was solved on hibernate side (#8127, https://hibernate.atlassian.net/browse/HHH-9751), which is not the case as HHH-9751 seems to be closed only as duplicate and the ticket it duplicates https://hibernate.atlassian.net/browse/HHH-9979 is still open. And anyway it is not sure if HHH-9979 is the reason for our problem at all.
So I close this ticket and handle the issue in #8127 or a newly created ticket.
