title: Primefaces imports, cannot be resolved
body: <p>Hi I am trying to draw a bar chart with primefaces.</p>
  
  <p>When I import below lines to my chart file,</p>
  
  <pre><code>import org.primefaces.model.chart.BarChartModel;
  import org.primefaces.model.chart.ChartSeries;
  </code></pre>
  
  <p>it gives error in first import saying that: </p>
  
  <blockquote>
    <p><code>The import org.primefaces.model.chart.BarChartModel cannot be resolved</code></p>
  </blockquote>
  
  <p>But it doesn't give error in second import. What am I doing wrong and how should I solve it?</p>
  
  <p>Thank you.</p>
