This is a follow up to the following comment from two months ago for visibility, as the original issue was marked as fixed.
https://support.skipper18.com/2485/fixed-gedmo-sluggable-generates-incorrect-yml-field-format?show=2490#c2490
Gedmo Tree arrays are invalid, outputting as:
gedmo:
treeLevel:
... instead of this:
gedmo:
- treeLevel
https://github.com/Atlantic18/DoctrineExtensions/blob/master/doc/tree.md#yaml-mapping-example
This is present on at least the treeLeft, treeRight, treeLevel and treeParent mappings. The issue causes major problems using Skipper on large schemas, as we have to manually revert lots of files that are affected by this in version control every time we export to ORM.
