PShape disableStyle() does not work in class

I have a Particle class that uses a SVG file to display graphics. What I want to do is to randomize the stroke and fill color for each particle using disableStyle(), but it doesn't seem to be working. It always displays the original svg style. When I have a simple setup and draw structure without using a class, disableStyle works just fine.
Any help would be appreciated!!
