Henri Biestro updated JEXL-159:
-------------------------------
Fix Version/s: (was: 3.0.1)
3.1
> Difference in handling between Jexl expression evaluation and LazyDynaMap
> -------------------------------------------------------------------------
>
> Key: JEXL-159
> URL: https://issues.apache.org/jira/browse/JEXL-159
> Project: Commons JEXL
> Issue Type: Bug
> Affects Versions: 2.1.1
> Reporter: Mike Day
> Fix For: 3.1
>
>
> LazyDynaMap seems to support a full stop in the attribute name, but the Jexl
> expression evaluation expects this to signify a nested object.
> The second test below fails, even though the first assertion is correct.
> Please can you take a look?
> {code}
> public class JexlTest {
> @Test
> public void testUnderscoreInName() {
> JexlEngine jexl = new JexlEngine();
> String jexlExp = "(x.length_mm * x.width)";
> Expression e = jexl.createExpression( jexlExp );
> JexlContext jc = new MapContext();
> LazyDynaMap object = new LazyDynaMap();
> object.set("length_mm", "10.0");
> object.set("width", "5.0");
> jc.set("x", object );
> assertEquals(null, ((Double)e.evaluate(jc)).doubleValue(), 50d, 0d);
> }
> @Test
> public void testFullStopInName() {
> JexlEngine jexl = new JexlEngine();
> String jexlExp = "(x.length.mm * x.width)";
> Expression e = jexl.createExpression( jexlExp );
> JexlContext jc = new MapContext();
> LazyDynaMap object = new LazyDynaMap();
> object.set("length.mm", "10.0");
> object.set("width", "5.0");
>
> assertEquals(null, object.get("length.mm"), "10.0");
> jc.set("x", object );
> assertEquals(null, ((Double)e.evaluate(jc)).doubleValue(), 50d, 0d);
> }
>
> @Test
> public void testFullStopInNameMakingSubObject() {
> JexlEngine jexl = new JexlEngine();
> String jexlExp = "(x.length.mm * x.width)";

> JexlContext jc = new MapContext();
