Draggable: constrained axis option returns incorrect position

[joshco]

when using draggabls with axis : 'y', it will constrain the movement of the entity visually. however, if the mouse is moved along the 'x' axis, the ui.position.left will return the delta of the mouse move. The expected result is 0, ie no movement.

repros with Jquery 1.5.2

I have the exact same problem. Created this jsfiddle to illustrate ​http://jsfiddle.net/Znarkus/m27CK/

Scott, even though I marked this as open, this might simply be a documentation issue. Should ui.position be constrained if there is a containment, or should it always track the mouse, and not the element?

[Scott González]

ui.position should be the constrained value. Users are allowed to modify the value in order to implement custom constraints, which would affect the value in later event handlers; so there's no reason that built-in contraints shouldn't modify the value directly. However, there is a question of whether built-in constraints should run before or after user-bound event handlers.

#9188 is a duplicate of this ticket.

Draggable: apply axis options to position instead of style. Fixes #7251 - Draggable: constrained axis option returns incorrect position.
