Re: [Simple-support] cannot use @Convert with @Attributes!?...

[-=}\\*/{=- <rui...@gm...>]

for now i'm going with JavaBean workaround...

  private Pattern match;
  @Attribute
  public String getMatch() {return match.pattern();}
  @Attribute
  public void setMatch(String re) {match = Pattern.compile(re);}

... but this makes me write it every time.
