Re: textfield tag not allowing blanks

Rechecking this, it seems to be a java templates thing (thought I had 
switched to std when checking!) where it uses .isNotBlank(..) where to 
make it comparable to std it should be .isNotEmpty(..)

org.apache.struts2.views.java.Attributes

public Attributes addIfExists(String attrName, Object paramValue, 
boolean encode) {
         if (paramValue != null) {
             String val = paramValue.toString();
             if (StringUtils.isNotBlank(val))
                 put(attrName, (encode ? 
StringUtils.defaultString(StringEscapeUtils.escapeHtml4(val)) : val));
         }
         return this;
  }

Will do a pr.

Thanks
