      Description

      I'm using Pivot as the user interface to an enterprise application. I want my users to be able to control applicaiton settings through the UI, such as where to save output files. In this particular case, the users want to use a network share accessed via a UNC path ("\\server\share").

      In testing, I discovered a NPE was being logged when I ran the following code:

        FileBrowser browser = ... //assume the browser is shown
        String path = ... //UNC path, such as "\\server\share" (escape slashes removed for legibility)
        java.io.File directory = new java.io.File(path);
        if (directory.exists()) {
            browser.setRootDirectory(directory);
        }
      

      The exception stack trace is:

      java.lang.NullPointerException
      at org.apache.pivot.wtk.skin.terra.TerraFileBrowserSkin$2.selectedItemChanged(TerraFileBrowserSkin.java:610)
      at org.apache.pivot.wtk.ListButton$ListButtonSelectionListenerList.selectedItemChanged(ListButton.java:131)
      at org.apache.pivot.wtk.ListButton.setSelectedIndex(ListButton.java:514)
      at org.apache.pivot.wtk.ListButton.setSelectedItem(ListButton.java:532)
      at org.apache.pivot.wtk.skin.terra.TerraFileBrowserSkin.rootDirectoryChanged(TerraFileBrowserSkin.java:955)
      at org.apache.pivot.wtk.FileBrowser$FileBrowserListenerList.rootDirectoryChanged(FileBrowser.java:44)
      at org.apache.pivot.wtk.FileBrowser.setRootDirectory(FileBrowser.java:127)

      Stepping through the code, it appears as though TerraFileBrowserSkin tries to select the drive by looking for path separators (slash characters), but it gets thrown off by the leading slashes in the UNC path.
