The "" ID is used for the root, and your tree IDs must always be unique. By specifying that "" is the child of another node you have created a circular reference in the hierarchy and therefore an infinite loop.

Thanks for the quick response, I can work around it. Our application uses the string tree to represent network data (i.e., OpenConfig YANG model as JSON encoded text RFC 7951), the leaves of the JSON tree is the value and JSON supports null or "". I understand the []string is used to look up the child tree ID in map, in the future, it would be nice the []string could be []interface e.g., an interface supports GetValue() or GetIndex() to distinguish between leaf value or index to another branch.

For now, I just leave the branch empty when no data present. Let me know if this can be enhanced in the future and I will close it after your response. Thanks

1 more issue in using tree to represent JSON caused by the unique tree node id constraint, the following valid json cannot be represented in the map[string][]string for NewTreeWithStrings() { "list": [ {"foo": "123"}, {"foo": "456"} ] }

Separation of the tree node display label and tree node id seems necessary to make it work, any suggestion? Thanks

[dliu2223]

1 more issue just found with following data, when B is selected, C value ("leaf") disappear, again, the "leaf" is a value which has no branch defined in the map. data := map[string][]string{ "": {"A"}, "A": {"B", "C"}, "B": {"leaf"}, "C": {"leaf"}, } If this is also a expected behavior, it creates major issues for working on JSON data, please advise. Thanks

Correct, the NewTreeWithStrings is just a shorthand where the content can also be the unique ID. for non-unique node data you will need to use NewTree or NewTreeWithData. The latter can take a binding.StringTree where you will see the id and the value are indeed separated.

the "leaf" is a value which has no branch defined in the map

In this demo you have used the ID "leaf" twice - which is not unique. A common way to work with this would be to put the parent ID as a prefix to a child so the path is unique even though the final node id is the same. As with a file path where two files have the same name in different directories.

I'm closing this issue as I don't think its the responsibility of 'widget.Tree' to function with infinite loops in the data source.
