Setting icons on XTabbedPane doesn't seem to work

[dbrgn]

This works:

<label id="headericon" icon="icons/books_medium.png" />

This does not work:

<tabbedPane id="tabbedPane" constraints="BorderLayout.CENTER" tabPlacement="TOP" icons="icons/books_medium.png,icons/books_medium.png,icons/books_medium.png">

There are 3 vbox elements contained in the tabbedPane.

When setting the icons on the element directly using setIcons, an exception is thrown.

tabbedPane.setIcons("icons/books_medium.png,icons/books_medium.png,icons/books_medium.png");

Exception in thread "main" java.lang.NullPointerException
    at org.swixml.converters.ImageIconConverter.conv(ImageIconConverter.java:99)
    at org.swixml.XTabbedPane.setIcons(XTabbedPane.java:216)
    at application.ui.BookMaster.onInitialize(BookMaster.java:115)
    at application.ui.BookMaster.<init>(BookMaster.java:94)
    at application.InitApp.main(InitApp.java:16)

When that happens (ImageIconConverter.java line 99) the localizer element is null. That might be the problem (or a symptom of the real problem).

I'm using the current SwiXML 2 downloaded from your website.

As a sidenote, this works.

// Set tab icons
public JTabbedPane tabbedPane;
tabbedPane.setIconAt(0, new ImageIcon("res/icons/user.png"));
tabbedPane.setIconAt(1, new ImageIcon("res/icons/book.png"));
tabbedPane.setIconAt(2, new ImageIcon("res/icons/book_next.png"));
