ItemFileReadStore too much recursion error when item points to parent

[bht]

The tree fails if raw items have parent references.

May be I misunderstand the MVC architecture of the tree.

I am (possibly incorrectly) expecting that the model can work with a model object that is useful in the application context beyond simply containing an ID and a label.

Otherwise I could imagine that the API would be much simpler, just expecting a simplified copy of the application model, perhaps a tree of nodes with only IDs and labels instead of ItemFileReadStore and TreeStoreModel.

In my case, every node model object needs a reference to its parent node which IMHO is a very common thing to do.

Please refer to the attached testcase.

Passing ticket to Jared but I think you are misunderstanding. Items need to be simple hashes (often mistakenly referred to as "JSON"). Typically you would implement a parent "pointer" by listing the id of the parent, like:

{id: "SF", parent: "CA"}

Your usage is incorrect.

1.) You're using a read-only store, you should not be modifying its contents like you are doing. If you want a modifiable store, use the write store: ​http://docs.dojocampus.org/dojo/data/api/Write#newitem ​http://docs.dojocampus.org/dojo/data/ItemFileWriteStore

2.) If you want to point to other items, then you need to use _reference structures, not direct item instances. See docs: ​http://docs.dojocampus.org/dojo/data/ItemFileReadStore#item-structure-examples
