[Commons Configuration] using setProperty for element on XML plist
I have been banging my head against the wall for hours trying to
write a <data/> element back into an OSX XML plist file. I use the
following to successfully read the element:
byte[] tmpByte = (byte[])settings.getProperty("node.name")
I then modify it but I cannot for the life of me figure out how to
cast it and write it back into the file using setProperty(). I'm at
the point where I Base64 encode it and write it out as a string but I
cannot get it back into <data>. I have looked through the junit
tests, javadocs and online and the closest thing I found was a nested
class with an addDataValue() method that looks like it's built for
this but it warns that it's for internal use by the digester.
Thanks for reading, if anyone can provide a pointer I would be grateful.
Thanks,
- Brian

Done. Yes, with a call to setDetailEvents(false) nested events can be
disabled. As it is implemented now, the setProperty() method triggers
only SET_PROPERTY events.

Thank you. Is there a mechanism to disable the clear and add events ?

I think so, I haven't tested this case yet.

Okay, I will have a look and write test cases for the events. From a
first glance it seems that CLEAR_PROPERTY and AND_PROPERTY events are
thrown instead of a SET_PROPERTY event.
I haven't looked into this issue in detail, but wouldn't the
addProperty() methods be affected, too?

I commited a fix for this bug, it affected both plist configurations.
Oliver could you review my change please ? I'm not familiar with the new
event notification stuff, I don't know if the right events are fired
with this fix.

I reproduced this issue, a byte[] is transformed into a list of integers
by HierarchicalConfiguration.setProperty(). This code :
FileConfiguration config = new XMLPropertyListConfiguration();
config.setProperty("foo", new byte[] { 1, 2, 3, 4 });
config.save("config.plist");
generates this :
<plist version="1.0">
<dict>
<key>foo</key>
<integer>1</integer>
<key>foo</key>
<integer>2</integer>
<key>foo</key>
<integer>3</integer>
<key>foo</key>
<integer>4</integer>
</dict>
</plist>
instead of
<plist version="1.0">
<dict>
<key>foo</key>
<data>01020304</data>
</dict>
</plist>
I don't know how to fix this easily. Maybe by adding a flag in
HierarchicalConfiguration to prevent the arrays from being split into a
list of nodes ?

Brian,
I haven't used XMLPropertyListConfiguration myself. But from a short
glance at the code I fear that there could be a bug related to the
handling of arrays. What exactly is the result when you call
setProperty() with the modified byte[]?
