how do you use the icon attribute at the treeNode? I have images (as png) in a directory resources web/resources/images/*.png. How do I replace the default icons used in the tree with my own? Is it ok to only refer to the name of the image in the icon attribute, like this:
<r:treeNode icon="myIcon.png" type="entityNode">
or do I have to do a lookup in my backing bean somehow?
