Sandro Martini commented on PIVOT-880:
--------------------------------------
Hi all,
after some tests with the pivot_880,bxml test case (that's using the
FileBrowserSheet instead, but it's the same), I had to do some small updates to
the test case and to FileBrowserSheet : Committed revision 1408247 , noe I'll
commit even in trunk.
@Roger, if you run this test case, you can see that now all works, but the
drive letters lists local drives and not the network server (which is the first
option in folders list) ... what do you think ?
> NPE when calling FileBrowser.setRootDirectory using a UNC path

> Key: PIVOT-880
> URL: https://issues.apache.org/jira/browse/PIVOT-880
> Project: Pivot
> Issue Type: Bug
> Components: wtk-terra
> Affects Versions: 2.0.1
> Environment: Windows XP with network shares
> Reporter: Steven Swor
> Assignee: Roger Whitcomb
> Priority: Minor
> Fix For: 2.1, 2.0.3
>
>
> 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.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.
