One way round this would is to put the above line in an openStack  
handler instead of preopenStack.

Another way might be to set the traversalOn property of the fields to  
false. (Which might not be what you want.)

I think the problem is that Rev will focus on the first control with  
traversalOn *after* the preOpenStack handler runs. If ths control is  
a list field, it will hilite one of the lines (not sure why it's the  
last line in your case, it's the first here).
