I have had this problem for a while, but my custom AbstractTreeNodes are not sorted properly in Project view. If I do not override getWeight(), it uses a weight of 30, and my custom nodes are below the non-custom node file nodes. If I set it to twenty, which I believe is the standard number for psi files, files are sorted in a way I cannot figure out.
The files are in three runs of alphabetical order. The files in each section are consistent (They do not change between restarts), but I cannot figure out why some are a-z(1) others are a-z(2) and others are a-z(3). The files in each section are of similar file types, and have some upper and some lowercase names, and some are directories. Here is an example image:
As you can see, the files in the screen shot go E,F,G,I,E,G,I. I can not figure out what is happening.
The files are properly sorted in Project Files view.
If I override getWeight() and return 21, the folders and non-custom nodes are properly sorted, and then my custom nodes are properly sorted beneath that.
Is there another method I should override or another value to set?
