In this case, an ICE While loop wasn’t working as expected.
The customer was using Max Repeat to do something like this, but in ICE:

x = 2
cond = x > 0

i = 0
while cond:
	print i
	i = i + 1
	if i > 10: break

Unfortunately, in ICE, the While loop was never executed.

It’s not a problem with the While loop, it’s a problem with the ICE tree evaluation (it’s a bit too lazy). I’ve seen things like this before, and I usually create a separate ICE tree to workaround it:

On the mailing list, Guillaume suggested a couple of other workarounds. First, use Delay Set Data.
The word “Delay” in the node name throws me off…I wouldn’t think to use it, but after reading up on it, I can see why you would think to use that node (it does evaluation).

If you set the condition boolean in the While loop, that works too:
