Hi to all
i create the following simple code. Using directory choose cause an error
The same code using FileChooser works without error.
Maybe a bug or something i'm missing?
Using the first example, when the button that activates the DirectoryChooser is pressed, an error is raised but the directory window is shown, and is possible to choose one. After clicking ok the correct folder is logged, but another error is raised closing the program.
This is the complete log of the error:

Sub btnFolder_Click
Dim dc As DirectoryChooser
dc.Initialize

Dim folder As String = dc.Show(B4XPages.GetNativeParent(Me))
