8578	"this.getWindow().$.getComputedStyle(this.$, \""\"") is null"	scott schmitz		"I an seeing the following error:
this.getWindow().$.getComputedStyle(this.$, \""\"") is null

userAgent:Mozilla/5.0 (Windows NT 6.1; WOW64; rv:8.0) Gecko/20100101 Firefox/8.0

The code in question is located at element.js line 502.

I am recommending that the code change from:

return this.getWindow().$.getComputedStyle( this.$, '' ).getPropertyValue( propertyName );

to

return this.getWindow().$.getComputedStyle( this.$, '' ) ? this.getWindow().$.getComputedStyle( this.$, '' ).getPropertyValue( propertyName ) : null;

that will fix the problem.

thanks,

Scott Schmitz."	Bug	closed	Normal		General		expired	Firefox
