Bug: Amaya does not preserve Jakarta Velocity template language statements

I'm using Amaya 4.3.2 to design some Velocity templates, using statements
like

   #foreach( $item in $items )
      The item name is $item.name<br>
   #end


Sometimes Amaya will strip out the statements beginning with "#" - I believe
it happens when I look at the document in structure view, and/or when I save
the document to disk.
