Creating Slider in FlexJS

[Lane]

I'm working with Flashbuilder 4.7 and FlexJS 0.7.0 on Windows 10. The 
following code generates a slider on the Run command. However, it does not 
generate a slider when I do a release build. Is there something very obvious 
that I am missing?

<js:Slider id="circuitsSlider" width="800" x="20" y="200"
           minimum="0" maximum="242" snapInterval="1" 
mouseUp="sliderChange()"/>

Thanks so much,

Lane.
