i've spend 2 days on this problem without solution.
I've redone the entire project two times starting from the HR example, applying my own model.
Same old error. If i try to use my custom folder as root, i got an error of Invalid Virtual Folder.
The stacktrace says that the exeption is started when WorkDesk tries to get the semi-virtual folders as childs.
Infact, if i ignore the error and extend manually the tree it works, and if i went back to search and click again to linked folder, it opens my Dossier Plugin without error.
It just can't get the list of virtual folder if is my custom folder. But my template works, i'm quite sure, i checked tons of times.
Is there a bug here?
Deko i can provide my files if it can help!
