[jira] [Commented] (PIVOT-880) NPE when calling FileBrowser.setRootDirectory using a UNC path

["Sandro Martini (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/PIVOT-880?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13493825#comment-13493825 ] 

Sandro Martini commented on PIVOT-880:
--------------------------------------

Of course a workaround is to map the sahre to a drive letter, just to avoid the NPE ... in the meantime we look at it, if there is a simple solution (for 2.0.x, now I start to look), otherwise we have to fix in 2.1 .

Roger, you are currently working on FileBrowser ... what do you think ?

> 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:
> {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);
>   }
> {code}
> The exception stack trace is:
> {quote}
>   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.FileBrowser$FileBrowserListenerList.rootDirectoryChanged(FileBrowser.java:44)
> 	at org.apache.pivot.wtk.FileBrowser.setRootDirectory(FileBrowser.java:127)
> {quote}
> 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.
