<@U91Q93944> ok, this is a cut down version of what i'm trying to do. Quite possibly I'm going about this the wrong way. Quite simply, if you change the root folder and run. All is well if you click onto a parent first, the children are then gathered nicely. However, if you click the expansion first, they do not. I've tried many different versions of populate and just can't fathom the errors. I'm not quite sure how the parameters are passed when in { } (which I assume are lambda function).. So I guess I need to go read up on that. This was all pretty straightforward until I got to the populate function.
