querying deformerSet components from within a deformer creates a cycle

[vince touache]

hi guys, 

I'm working on a deformer I don't want to use MItGeometry to iterate on my vertices (I need to work in a different order).

So instead, I'd like to directly query the deformerSet and get the component list from there, e.g.

MObject oThis = thisMObject();

MFnGeometryFilter fnThis(oThis);

MFnSet fnSet(fnThis.deformerSet());

MSelectionList members;

fnSet.getMembers(members, false);

But calling fnSet.getMembers() results in a cycle (but no crash) inside maya.

1. Any idea how I could get the components affected by my deformer, if I can't do it this way?

2. I'd like to understand why this is creating a cycle... the deformerSet is not related to the outGeom, this is just a set, so how querying its members can introduce a cycle?

Thanks for your help =]
