title: Why only one row is showing in report?
body: <p>In MySQL workbench I get 3 rows:</p>
  
  <pre><code>mysql&gt; select * from person;
  +-----+------+
  | ID  | NAME |
  +-----+------+
  | A01 | A01  |
  | A02 | A02  |
  | A03 | A03  |
  +-----+------+
  3 rows in set (0.00 sec)
  </code></pre>
  
  <p>but when I use jrxml and show to pdf</p>
  
  <p>I just can get a one row</p>
  
  <pre><code>+-----+------+
  | ID  | NAME |
  +-----+------+
  | A01 | A01  |
  +-----+------+
  </code></pre>
  
  <p>and this's my jrxml</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="UTF-8"?&gt;
