Attempt to add children to leaf component in tree results in "targetlump is undefined" error

Below is a section of component tree - in it, "title-plain" is a leaf node, but is presented with children, because its markup contains further nodes. This triggers the "erroneous branch", currently at line 1778 of the renderer:

if (component && component.children !== undefined)

{ renderContainer(component); renderindex = lump.close_tag.lumpindex + 1; }

which can never execute correctly since it does not supply a target branch point. Behaviour in this case should be clarified and a reasonable diagnostic issued.

var fullTree = {
children: [
// The colon ( at the end of the rsf ID identifies the component as a repeating
// component. In this full tree, there is one object for each repeated component.
{
ID: "resource-item:",
children: [ {
ID: "title-plain",
decorators: [

{ type: "addClass", classes: "level0" }

],
children: [ {
ID: "title-link",
linktext: "My Workspace",
target: "/user/jimeng/",
decorators: [{
attrs:

{title: "Folder"}

}]

}, {
ID: "title-image",
target: "../images/dir_closed.gif",
decorators: [{
attrs:

{alt: "Folder"}

}]
}]

} ]
