Przemo Pakulski updated JCR-562:
--------------------------------

    Attachment: JCR-562.patch

The attached patch contains fix and following test case :

    public void testLogicalExpression() throws Exception {
		Node foo = testRootNode.addNode("foo");
		foo.setProperty("a", 1);
		foo.setProperty("b", 2);
		foo.setProperty("c", 3);
		Node bar = testRootNode.addNode("bar");
		bar.setProperty("a", 0);
		bar.setProperty("b", 2);
		bar.setProperty("c", 0);
		Node bla = testRootNode.addNode("bla");
		bla.setProperty("a", 1);
		bla.setProperty("b", 0);
		bla.setProperty("c", 3);		
		testRootNode.save();

		String sql = "SELECT * FROM nt:unstructured WHERE a=1 and b=2 or c=3";
		Query q = superuser.getWorkspace().getQueryManager().createQuery(sql, Query.SQL);
		QueryResult result = q.execute();
		checkResult(result, new Node[]{foo, bla});		
			
		String xpath = "//*[@a=1 and @b=2 or @c=3] ";
		q = superuser.getWorkspace().getQueryManager().createQuery(xpath, Query.XPATH);
		result = q.execute();
		checkResult(result, new Node[]{foo, bla});
	}

> executing query: //*[@a=1 and @b=2 or @c=3] leads to creating wrong query tree. The builded tree looks like for query: //*[@a=1 and @b=2 and @c=3](see attachement). using brackets resolves the problem, but without brackets output query is different from input query. When AND and OR are switched(so the OR is in first palce - //*[@a=1 or @b=2 and @c=3]) everything is ok.
