RE: Barracuda: IterativeModel and Veto_If_Null

MessageHi Thuong,

From myu recollection, I don't think Veto_If_Null should be getting
processed if the first Iterate_Next doesn't come back as having values. What
should happen is that it should jumpt to the Iterate_End and continue
processing from there. But I don't see that end directive in your
markup...is it there somewhere?

  Subject: Barracuda: IterativeModel and Veto_If_Null


  Q. if I have an iterative model that is not rendering any items (i.e.
iterating over an empty list), would every directives within the "boundary"
of the iterative_start and iterative_end be skipped?

  for example:

  <ul>
      <li class="Dir::Iterative_Start.MyModel Dir::Iterative_Next.MyModel">
          <span class="Dir::Get_Data.MyModel.SomeData">..</span>
      </li>
      <li class="Dir::Veto_If_Null.MyModel.showTotal">Total</li>
      <li class="Dir::Iterative_Next.MyModel Dir::Discrd">...</li>
  </ul>

  would the "Veto_If_Null" directive gets executed even if the iteration
never takes place (because of zero-sized list)?  From what i'm seeing, it
seems like it does.  I just don't know if this is expected or bugs in my
code.


  thanks!
