RE: Barracuda: IterativeModel and Veto_If_Null

Sorry, the last <li> tag should have the Iterative_End directive, not
Iterative_Next.  This is simplified version code of my template.
 
hm ... if your recollection is correct, then there must be something
wrong with my model.  From debugging my code, I noticed that the
Veto_If_Null.MyModel.showTotal was being processed even when the list to
iterate over has size equals to zero.  I'll double check.
 
thanks!

	Hi 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?

		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!
