title: XPages Multiline Edit Box validation fails on blank lines
body: <p>I'm getting a failure when attempting to validate required content for a Multiline Edit Box control.   I'm using simple required validation only, as follows:</p>
  
  <pre><code>&lt;xp:inputTextarea
  id="subject1"
  rows="5"
  style="width:99%"
  value="${javascript:'#{compositeData.requestDocument.subject}'}"
  multipleSeparator="#{javascript:@NewLine()}"
  required="true"&gt;
  &lt;xp:this.validators&gt;
      &lt;xp:validateRequired
          message="Please explain the issue for which you need help." /&gt;
  &lt;/xp:this.validators&gt;
  </code></pre>
  
  <p></p>
  
  <p>If I enter multiple lines WITHOUT blank lines the validation succeds:</p>
  
  <p>"foo line 1
  foo line 2
  foo line 3"</p>
  
  <p>but if I enter multiple lines WITH a blank line the validation fails:</p>
  
  <p>"foo line 1</p>
  
  <p>foo line 3"</p>
  
  <p>Any ideas on what I'm doing wrong?</p>
