[opencms-dev] cmstag:contentcheck ifexists suggestion

[Jorge González]

Hi list:

The <cmstag:contentcheck ifexists="xxx"> tag returns "true" if the content
does not exist, that is, in the case of an html attribute.

An empty html field is automatically completed with a <br /> by the xml
content editor page.

I'm using this method, and it works as expected:

  public boolean isEmpty(String str) {
    if(str == null) return true;
    else if("".equals(str)) return true;
    else if("<br />".equals(str.trim())) return true;
    else if("<br />".equals(str.trim())) return true;
    else
       return false;
  }
