Timeline initial Lane sorting

[Hirn]

Dear developers.
I have a tree displayed.

I want to display the tree items in the same order in the Timeline, while I use the following code, but I have shuffled Lanes in an order unknown to me.

ListGrid tasksLineProps = new ListGrid();
tasksLineProps.setCanSort(false);
tasksLine = new Timeline();
tasksLine.setAutoChildProperties("timelineView", tasksLineProps);
......
......
TreeNode courseItemNode = projectTree.findById(courseItem.getAttribute(CONSTANT._ID));
firstLevel = projectTree.getLevel(courseItemNode);
Record[] lanes = projectTree.getAllNodes(courseItemNode);

tasksLanes = EvolutionDataSource.castRecordsToLanes(lanes);
tasksLine.setLanes(tasksLanes);

In previous versions, this was not the case. The order was maintained.

Dear developers.
Do you have any thoughts on this problem?

We'll take a look today and update here

We tested this out and we're not able to reproduce any kind of sorting problems. We tried calling setLanes() before and after draw(), resorting the Tree and then recreating the timeline or just re-applying the new node-order to the existing one. And everything seems to work as expected.

It's not clear what the problem is, without seeing more code, but one thing you could check is the code in, and the order of the items before and after you call, castRecordsToLanes() - not all Sets guarantee order, and our equivalent test-code just loops over the nodes as-sorted and creates new Lanes in a Lane[]

We'll likely need to see a list of affected browsers and some runnable code that shows the issue in order to help further.

I will try to prepare a working example in the next day.
It is strange that everything works correctly in the LGPL Version SNAPSHOT_v13.0d_2020-08-09, but not in the LGPL Version SNAPSHOT_v13.0d_2021-05-06

We switched to the Pro version in May and I can't say which version stopped workin

I have prepared an example that displays my problem

Thanks for the test case - there was indeed a bug, introduced with some recent optimizations and resulting in an internal loop over an unordered map of lanes, rather than the array of lanes.

We've made a change to address it - please retest with a build dated June 29 or later.
