Henri Biestro commented on JEXL-225:
------------------------------------
ObjectContext is not really meant to work with a map as inner object; the 'has'
method in particular is not 'precise' enough since it only verifies it can
muster a JexlPropertyGet.
> Incorrect invoking methods with ObjectContext
> ---------------------------------------------

> Key: JEXL-225
> URL: https://issues.apache.org/jira/browse/JEXL-225
> Project: Commons JEXL
> Issue Type: Bug
> Affects Versions: 3.1
> Reporter: Vyacheslav Shago
> Assignee: Henri Biestro
>
> After apply fix in [JEXL-190|https://issues.apache.org/jira/browse/JEXL-190]
> folowing code doesn't work anymore:
> {code}
> public class Example {
> public static void main(String[] args) {
> JexlEngine jexl = new JexlBuilder().create();
> ObjectContext<Foo> context = new ObjectContext<>(jexl, new Foo());
> JexlExpression expression = jexl.createExpression("bar()");
> System.out.println(expression.evaluate(context));
> }
> public static class Foo extends HashMap<String, Object>{
> public String bar(){
> return "bar";
> }
> }
> }
> {code}
> Also doesn't work this code:
> {code}
> public class Example {
> public static void main(String[] args) {
> HashMap<String, Object> functions = new HashMap<>();
> functions.put(null, new DefaultFunctions());
> JexlEngine jexl = new JexlBuilder()
> .namespaces(functions)
> .create();
> ObjectContext<Object> context = new ObjectContext<>(jexl, new
> Object());
> JexlExpression expression = jexl.createExpression("bar()");
> System.out.println(expression.evaluate(context));
> }
> public static class DefaultFunctions {
> public String bar(){
> return "bar";
> }
> }
> }
> {code}
> Output:
> {code}
> Example.main@1:4 unsolvable function/method 'bar'
> {code}
> note: with MapContext all working correct
