Thanks for posting, Glad it helped! To be honest, I’m not sure- I got lucky finding that amongst the masses of disorganised forum posts and I pasted it straight in and it just worked.

I can’t say for sure if your interpretation of the code is right without knowing what the GetTreeServiceUrl method does; that might all I can say is that I have that same code snippet up and powering a custom “job application” section on the backend of bookpoint.co.uk and all is live and working as expected.

Its a shame really- as much as I like what the Umbraco guys have done, I found the documentation to he a massive let down to the project.

The child node needs to have its parent id set as the source.

Unless I’m reading it wrong (I’m not using dictionaries) I think this line may be wrong:

xNode.Source = di.hasChildren ? this.GetTreeServiceUrl(di.id) : “”;

It loos like its setting its parent to itself. However, I don’t have a way to test this specific case.
