I'm trying to display XML data in a tree. Because of the way
the XML looks, I needed to write a custom data descriptor (I'll
explain the XML structure at the end of the post) with custom
Now I've got the problem that everything works fine, but
empty branches will still have the disclosure icon displayed. So
apparently the data passed to the default itemRenderer is not
"delivered" by the data descriptor - or the data descriptor
delivers something to the renderer in a way that's incorrect.
Either way, the TreeItemRenderer will show
_listData.hasChildren to be true, while the data
hasChildren will show it to be false.
Assuming the data descriptor is okay, is there any way to
access the original XML from within a custom treeItemRenderer so
that I can "check for children myself"?
(on a second issue, I would also need to display a specific
image with each tree leaf, depending on how an XML attribute of the
leaf is set - similar to the Windows Explorer showing different
icons for different file types - again, this would only work if I
had access to the XML structure from within the renderer)
Any help is much appreciated,
Branches and Leaves are both received as <folder> tags.
Both leaves and branches can have <property> tags, which are
not to be displayed. The only difference between a branch and a
leaf is that the leaves have a <property
name='url'>url</property> tag, while the branches do not
have property tags with a "name" attribute set to "url".
/not to be displayed at all <folder id="firstSubfolder">
/this should be an empty subfolder <property
