Create a one tile stockpile. Clear all allowed items. Then select a single weapon or item of apparel that you know exists on the map. Ensure that hit points are 0-100% and any quality is allowed. Then click a pawn and right click the single weapon or apparel. They cannot haul it to to the stockpile. The message, no configured space to haul it to message is displayed.
Did you unpause for a few seconds and try again? I've had a similar experience with all new storage areas for several alphas but after a few seconds of runtime it self-resolved.
The pawn needs a tick to recognize that the stockpile has changed, toggling the pause button should resolve it.
Please respond if this is not the case, as that might be a bug that was overlooked.
I've updated the bug title. Thanks for reporting. I'll move this to Mantis now.
