Accumulate Node creates Loop.

[vanjoe]

The definition of the Graph object says the it "Does Not loop back" Does a Accumulate node not loop back to it's input?

Yes, you are correct that the bidirectional parameter on the Accumulate nodes does technically cause a cycle. There are some update rules in the specification to make sure the result is consistent. There is an active discussion in the working group about whether to remove or at least deprecate bidirectional parameters in a future version of the spec, although there are concerns about backward compatibility and an efficient alternate implementation of the Accumulate functionality.

Will be fixed in OpenVX 1.3.
