I can't fully understand your code at once. Could you explain the change you made in this PR? :)

[dayo09]

@jyoungyun Sure :-D

Do you remember that the explorer flickers and folds all the nodes whenever there are file changes? It's because it currently rebuilds all the nodes on file change event. Now, it's improved to build the related nodes. With this draft, you can see that it doesn't flicker anymore when you save cfg or delete some model files.

(1) On Cfg file change:

• it rebuilds the related model nodes.
  • parent node: if any parent node(base model) is added / removed, OneStorage updates the 'base model to cfg' map and 'base model node' infomation. and the nodes are rebuild
  • child node: if any child node (circle, log, etc... a.k.a products) is added / removed, OneStorage updates the 'cfg object' map and 'cfg node' information and 'product node'.

(2) On Product(circle/tvn/log, ...) delete:

• it rebuilds the related cfg node.
  • NOTE that multiple product nodes can be shown under multiple cfg file.
  • we need to find all the related cfg nodes and update the information ('cfg object' map and 'cfg node' information and 'product node')

It's all for change/delete. I am working on 'create' event.

Does this have nothing to do with folding whenever there is a file change? Because when I tested this PR, if I build cfg and create a new product file, it still folds. I thought this change is related to the folding issue. :)
