Dmitri Blinov commented on JEXL-302:
------------------------------------
Maybe I'm kicking a dead horse here, but can you please explain the logic
behind {{x.y[['z', 't']]}}
{code:java}
@Test
public void testLiteral() throws Exception {
JexlScript e = JEXL.createScript("x.y[['z', 't']]");
Set<List<String>> vars = e.getVariables();
Assert.assertEquals(1, vars.size());
Assert.assertTrue(eq(mkref(new String[][]{{"x", "y", "[ 'z', 't' ]"}}),
vars));
} {code}
Why do we expect the last "[ 'z', 't' ]" part? How is it differ from, for
instance, {{x.y['z' + 't']}} in a sense that both {{'z' + 't'}} and {{['z',
't']}} are just expressions?
> JexlScript.getVariables returns strange values for array access

> Key: JEXL-302
> URL: https://issues.apache.org/jira/browse/JEXL-302
> Project: Commons JEXL
> Issue Type: Bug
> Affects Versions: 3.1
> Reporter: Dmitri Blinov
> Assignee: Henri Biestro
> Priority: Minor
> Fix For: 3.2
>
>
> I can not understand the logic behind the current implementation of
> {{JexlScript.getVariables()}} method. From the documentation we know that the
> result should be the set of script variables. For the code
> {code:java}
> a[b][c]{code}
> it gives three variables {{a}}, {{b}}, {{c}}. So far so good. But for the code
> {code:java}
> a[b]['c']{code}
> it returns {{a}} and {{b c}}, where second variable has two fragments {{b}}
> and {{c}}. The documentation states that variables with multiple fragments
> are ant-ish variables, but I don't have any of ant-ish variables in the
> example, and {{'c'}} is not a variable, but a constant. I expect to get {{a}}
> and {{b}} as a result.
