title: Jaspersoft iReport Designer Stretch With Overflow not working if field is a group
body: <p>Using 4.5.0 for numerous reports, each using the same datafield SVC_METH_NM. Have no problem word wrapping (using Stretch With Overflow) the datafield SVC_METH_NM unless the field is a group. When the field is a Group, the data is truncated instead of wrapped. If I set the Evaluation Time to Now, which blanks out the Evaluation group, it wraps correctly (but the report doesn't display properly). I tried removing the fields in the line immediately below, and have tried playing with the Position Type and Stretch Type options, to no avail.</p>
  
  <pre><code>&lt;group name="ServiceMethodName"&gt;
  &lt;groupExpression&gt;&lt;![CDATA[$F{SVC_METH_NM}]]&gt;&lt;/groupExpression&gt;
  &lt;groupHeader&gt;
  &lt;band height="20"&gt;
  &lt;textField isStretchWithOverflow="true" evaluationTime="Group" evaluationGroup="ServiceMethodName"&gt;
  &lt;reportElement x="23" y="0" width="180" height="20" printWhenGroupChanges="ServiceMethodName"/&gt;
  &lt;textElement&gt;
  &lt;font isBold="true" isItalic="false"/&gt;&lt;/textElement&gt;
  &lt;textFieldExpression&gt;&lt;![CDATA[$F{SVC_METH_NM}]]&gt;&lt;/textFieldExpression&gt;
  &lt;/textField&gt;
  </code></pre>
  
  <p>Has anyone else run into this?</p>
