WowAce

What steps will reproduce the problem?
Take a color picker option that works perfectly fine without alpha.  Then change hasAlpha from false to true, and add defaultA and currentA to the array.

What is the expected output? What do you see instead?
Expected: there to be an alpha slider in the color picker, with the default/current values set
Instead: the color picker does not display in the options window, and an error is generated (below)

What version of the product are you using?
r41  (WoW-3.0-release-2)

Do you have an error log of what happened?

Please provide any additional information below.

The error is caused by two typos in "LibSimpleOptions-1.0.lua":

Line 864:
currentR = args.currentA

change to:
currentA = args.currentA

Line 911:
g = currentB,
b = currentG,

change to:
g = currentG,
b = currentB,

Also on line 740 change the end from: "hasAlpha and 1 - previousValues.opacity or 1"

to: "1 - previousValues.opacity"

This will prevent the opacity being changed to 1 when the cancel or esc button is pressed.

Regards,
