Joints rotate after I add constrains...

I end up with random joint rotations after I add constrains (especially if I add Orient constrain, or anything related to rotation).
The joints are properly oriented, and the transforms of the control objects are freezed.
Besides that, the joints decide to rotate 360 degrees, or 180 degrees.

My first question would be, why is this happening?
The second question: How to avoid this?

I haven't change the rotation order, or anything else (meaning everything is at the default setting), because I fairly new at rigging, I don't really understand how those things affect what I do...

Try the checkbox 'maintain offset'.

Constraints in Maya are buggy, I couldn't really tell you why it happens,,, but sometimes (usually on with orient constraints) you get a weird offset where it flips the object, bone , geometry, whatever 180 degrees. Sometimes you can trick the constraint by hooking up another object to the joint rotation via connection editor,,, then constrain that object back to the original controller you used in the first place. Dunno why, but it seems to fix the problem.



Werd.
