Date Tue, 07 Jun 2011 10:27:58 GMT

]

Johannes Stelzer updated JXPATH-151:
------------------------------------

    Description: 
Comparing a vaule to null using unequals (!=) yields false!
{quote}
        Map<String, Integer> m = new HashMap<String, Integer>();
        m.put("a", 1);
        m.put("b", null);
        m.put("c", 1);
        JXPathContext c = JXPathContext.newContext(m);
        System.out.println(c.getValue("a != b") + " should be true");
        System.out.println(c.getValue("a != c") + " should be false");
        System.out.println(c.getValue("a = b") + " should be false");
        System.out.println(c.getValue("a = c") + " should be true");
        System.out.println(c.getValue("not(a = b)") + " should be true");
        System.out.println(c.getValue("not(a = c)") + " should be false");
{quote}

Output using 1.3:
{color:red} false should be true{color}
false should be false
false should be false
true should be true
true should be true
false should be false


In 1.2 it works correctly!
