This sample works in Ivy: https://www.primefaces.org/showcase-ext/sections/gchart/basic.jsf;jsessionid=node0gzhije8myrwx1x5550c6oe8h0345257.node0

I did the following:

.xhtml

<pe:gChart value="#{data.chartModel}" title="How Much Pizza I Ate Last Night">
</pe:gChart>

data model

chartModel > org.primefaces.extensions.component.gchart.model.GChartModel

Java class

package test;
import java.util.Random;
import org.primefaces.extensions.component.gchart.model.GChartModel;
import org.primefaces.extensions.component.gchart.model.GChartModelBuilder;
import org.primefaces.extensions.component.gchart.model.GChartType;

public class ChartModelCreator  {

    private Random random = new Random();  
    private int mushrooms = random.nextInt(10);  
    private int onions = random.nextInt(10);  
    private GChartModel chartModel = null;

    public ChartModelCreator() {  
        chartModel = new GChartModelBuilder()
                .setChartType(GChartType.PIE)  
                .addColumns("Topping", "Slices")
                .addRow("Mushrooms", mushrooms)  
                .addRow("Onions", onions)
                .build();  
    }

    public GChartModel getChartModel(){  
        return chartModel;  
    }

}

ivy logic Directly after start() make an ivy script step, which applys

import test.ChartModelCreator;
ChartModelCreator creator = new ChartModelCreator();
in.chartModel = creator.getChartModel();

How das your model look like? Which browser version do you use?
