Where Used wikiWord="" leads to Exception

[starguy]

Hi,

the "Where used" Function may lead to the folowing Exception. Reason for this is an empty ("") wikiWord.

The method expandPrefix in fitnesse.wiki.WikiWordReference.java should be changed to something like:

public static String expandPrefix(WikiPage wikiPage, String theWord) { if(!theWord.equals("")) { if (theWord.charAt(0) == '^' || theWord.charAt(0) == '>') { String prefix = wikiPage.getName(); return String.format("%s.%s", prefix, theWord.substring(1)); } else if (theWord.charAt(0) == '<') { String undecoratedPath = theWord.substring(1); String[] pathElements = undecoratedPath.split("."); String target = pathElements[0]; for (WikiPage current = wikiPage.getParent(); !current.isRoot(); current = current.getParent()) { if (current.getName().equals(target)) { pathElements[0] = PathParser.render(current.getPageCrawler().getFullPath()); return "." + StringUtils.join(Arrays.asList(pathElements), "."); } } return "." + undecoratedPath; } } return theWord; }

Greetings
