jQuery UI Progress Bar Widget – upgrading to 1.8

If you are upgrading your jQuery UI build from 1.7 to 1.8 and you are using the Progress Bar widget, AND your progress bars break after the upgrade, make sure you are passing Number values, not String values to the “value” option of the Progress Bar plugin.

BROKEN IN 1.8: Passing String value to Progress Bar

WORKS in 1.8: Passing Number values
