It tries to get the expression from the text of  element - if null it then goes to try to get it from the expression attribute. Only trouble is the text is returned from getTextTrim() as "" rather than null so you never get to look at the attribute.
Ok, it's even a bit more sophisticated. In the current version 1.7 (committed February 7th) yet another attribute is taken into account: attribute decision on the element transition. I did not know that! In fact, this has been like this since earlier versions. Your bug is now at line 745; http://fisheye.jboss.com/browse/JBPM/jbpm.3In /jpdl/jar/src/main/java/org/jbpm/jpdl/xml/JpdlXmlReader.java?r=1.7
739 String condition = transitionElement.attributeValue("condition");
  | 740 if (condition==null) {
  | 741   Element conditionElement = transitionElement.element("condition");
  | 742   if (conditionElement!=null) {
  | 743     condition = conditionElement.getTextTrim();
  | 744     // for backwards compatibility
  | 745     if (condition==null) {
  | 746       condition = conditionElement.attributeValue("expression");
  | 747     }
  | 748   }
  | 749 }
Note that fixing this (or when using the element text rather than an attribute) will get the expression into the database, but then one still needs the additional check for isEmpty(), as explained in my earlier post, to actually evaluate the expression at runtime.
