[flexcoders] Tree nodes created from XML comments not selectable

[nikolajselvik]

Hi all,

There seems to be a problem with selecting tree nodes created by XML
comment elements in an XMLListCollection. The actual selection is made
but the visual cue or highlight is not set.. See example below. Why is
this happening? What would be the cleanest workaround?

Cheers,

Nick
