'animate' doesn't work for 'background-position' property in IE6-7

Reported by: Owned by:
Priority: undecided Milestone: 1.5
Component: unfiled Version: 1.4.3
Keywords: Cc:
Blocked by: Blocking:

Since I switched to jquery-1.4.3 the following code stopped working in IE6-7:

       'background-position' : '200px 0'

Now it causes the following error:

Invalid argument. jquery.js line 6573 character 5:[ fx.prop ] = (fx.prop === "width" || fx.prop === "height" ? Math.max(0, : + fx.unit;

At the same time, animation for properties 'background-position-x' and 'background-position-y' seems to be working fine.

_comment0: The documentation for [ animate] states \ >Shorthand CSS properties (e.g. margin, background, border) are not supported. \ \ Shorthand properties don't work equally across all browsers. For animating background-position in a cross browser way consider using the `bgpos`-cssHook from [ jquery-cssHooks]1289315342018520

The documentation for animate states

I'm not sure that 'background-position' is a shorthand property, but I found another condition that I missed:

All animated properties should be a ''single numeric value''

Thanks for the report, but this is not a jQuery bug. If you want to animate background position, you need to install a plugin that adds support for it.
