Steven Swor created PIVOT-880:
---------------------------------
Summary: 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
Priority: Minor
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:
{code}
java.lang.NullPointerException

org.apache.pivot.wtk.FileBrowser.setRootDirectory(FileBrowser.java:127)
{code}
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.
