When creating a plot using IVizService named as "ice-plot", a corresponding createPlot() method in CSVVizService is called by default, which returns a null pointer exception after consuming EAVP service in Vaadin. The exception was thrown at CSVProxyPlot.java in createProxySeries method where the style variable is assigned a value. The debugging revealed that null was passed to that method as an argument from CSVProxyPlot which in turn was passed from calling getIndependentSeries in reloadSeries method. Turns out, the getter returns independentSeries before it's set or assigned some value, hence null from the AbstractPlot.
