IK does not work

Description

Win 64, dell inspirion laptop, NVidia graphic Card

Please help : i'm trying to set the IK for bones. I'm preparing the chain of bones, then i'm disconecting parent of the last one ( alt-P) , rename it as an IK-bone. Then I'm choosing IK bone and the last in the chain ( with shift) then I'm trying to add constraint ( tracking / Inverse Kinematics).
Then I'm getting info: IK constaint can be added only to the bones !!! ( and sign: ! plus it does not work) What is wrong?! These are bones!
Is it a bug? Or am i doing something wrong? Help.
Rgst, Stefan.

Please send info to : stesta@wp.pl. s.staniszewski@humanist.com.pl, THX!

Hello,

IK is a bone constraint. You must switch to pose mode to add this constraint, and go to bone constraint tab (icon is chain links + bone), not constraint tab (icon is chain links only).
All bone constraints must be added on pose mode, not edit mode.

Cheers,

@Julian Eisel (Severin) Think you can closed as invalid now. I think I have no rights to perform that.

(if I choose Action = change status, I can't choose the new status, and preview is set to "Closed as resolved" ... Didn't try to Submit to see if I can choose status in next step.)

Julian Eisel (Severin) changed the task status from Unknown Status to Archived.Mar 5 2015, 1:13 PM

Okay, closing then. Thx for investigating @Julien DUROURE (julien) :) (afaik you should be able to close as invalid by choosing "Change Status" -> "Invalid" -> "Submit" without any special rights. Not sure why it fails for you)
