Dmitri Blinov commented on JEXL-306:
------------------------------------
Regarding second part of the question, consider the following example {code}x.y
? 1 : 2{code}
It returns 2 because x.y is undefined ant-ish variable. Another example that
returns 2 is {code}var x = {'a':1}; x.y ? 1 : 2{code}
My opinion is that we would expect predicted equal behaviour from syntactically
equal constructs. So yes - ternaries should protect from unsolvable properties.
> Ternary operator ? protects also its branches from resolution errors

> Key: JEXL-306
> URL: https://issues.apache.org/jira/browse/JEXL-306
> Project: Commons JEXL
> Issue Type: Bug
> Affects Versions: 3.1
> Reporter: Dmitri Blinov
> Assignee: Henri Biestro
> Priority: Major
> Fix For: 3.2
>
>
> Consider the following test case (suppose its added to IfTest)
> {code:java}
> @Test
> public void testTernaryFail() throws Exception {
> JexlEvalContext jc = new JexlEvalContext();
> JexlExpression e = JEXL.createExpression("false ? bar : quux");
> Object o;
> jc.setStrict(true);
> jc.setSilent(false);
> try {
> o = e.evaluate(jc);
> Assert.fail("Should have failed");
> } catch (Exception ex) {
> // OK
> }
> }
> {code}
> The expected behavior is to fail with {{undefined variable...}} because
> neither {{bar}} nor {{quux}} is defined
