Valid a file location after a user changes the directory

[SteveK]

The File search variable condition is executed only at the begining of the installation. I have a screen that lets the user change the desired directory and I do not have a way to validate that the files that are needed exist in this new location. I need a way to force the file search variables to execute again after a user changes a directory variable in a dialog screen.

Hi,
That would be a very useful addition, especially is one were producing patches or updates.
Thanks for the suggestions.
