Henri Biestro commented on JEXL-105:
------------------------------------
Thanks for the test case, bug is confirmed.
Culprit is Interpreter#visit(ASTArrayLiteral node, Object data) which
wrongfully considers an array literal as a constant evaluation.
> Array creation 2nd time requires duplication of JexlEngine

> JexlContext context = new MapContext();
> Expression selectExp = new JexlEngine().createExpression("[a.propA]");
> context.set("a", new A("a1", "p1"));
> System.out.println(Arrays.toString((Object[])selectExp.evaluate(context)));

> -->[p1]
> //selectExp = new JexlEngine().createExpression("[a.propA]");
> context.set("a", new A("a2", "p2"));
> System.out.println(Arrays.toString((Object[])selectExp.evaluate(context)));
>
> --> [p1] correct answer should be [p2]
