I've installed the 2.4.0 Infoblox plug-in and configured it's default NIOS to hit against. It seems to work just fine I can run worklows to add and remove subnets just fine.
However... when I use a build profile in vCAC to engage the state change workflows it attempts to run the wrapper workflows which all fail complaining about null errors as if something is not being set or passed along properly.
If I edit the child workflows that those wrappers are calling to and remove a step where it checks an attribute thats meant to see if a user explicitly declared what infoblox endpoint to use, then the children and thus the wrappers work fine. This seems like a bad solution, something is not right upstream.
Any ideas? I've got an infoblox case open I'm going to be working with them later today.
Entire stack:
vCAC 6.1 / VCO 5.5 / ESXi 5.5 / Infoblox plug-in 2.4.0 / Infoblox NIOS 6.11.latest
