Guys,
I'm trying to create a dialog which will request a list of images from
the server. The XML returns a list with a bunch of URLs. I'm trying to
use the URLs to build a list of thumbnails in the dialog. However, the
thumbnails I create don't show up on the dialog. I know that the images
are not being requested. Any help would be great:
<library>

<attribute name="imagepath"/>

<method event="onclick">
listener.changeBackground(this.getAttribute('bgid'),
this.getAttribute('imagepath'));
</method>
