[wix-users] Cancel Dialog and return nothing

[Stephen Griffiths]

I am currently building a custom wizard and one of the steps is to select a user specific directory to install the application into.
After selecting a new folder and clicking the Back button everything works as expected and the selected folder in the install location picker dialog is transferred back to the calling dialog box. However, I have also added a cancel button but whatever I try I cannot seem to get the original value of the install location to be transferred back to the calling dialog.

I have searched on the web for this but there aren’t many returns and what there are do not refer to the problem that I am having. This would lead me to believe that I am missing the bleeding obvious!

My dialog is shown below. Can anyone point out to me where I am wrong!

Many thanks for any help

Steve
