Is it possible to dynamically assign a file to the Tree tool?

[Martyn]

I have files that define hierarchical data structures (COBOL copybooks) and I am trying to set up an App that when the user has selected the file containing the copybook the user wants to filter - will be presented with the Tree for that copybook - and then based on the fields (or groups of fields) selected, a subset of the data structure is output. (The copybook file has had a key added to it to define the hierarchical structure as required)

I can get this to work with a fixed file specified in the Tree tool - but am not sure how to make this dynamic.

As you can see from the screenshot below, I tried using the File Browse tool as input to the Tree tool - but this doesn't seem to do anything.

The only other thing that I can think of doing is maybe making a chained App.

Any suggestions?

I believe a chained app is going to be your only option here.

First app will need to create the tree list file and the second app would read that file in.
