Henri Biestro commented on JEXL-147:
------------------------------------
On the 3.0 trunk, the issue as described does not occur:
{code}
public void test147() throws Exception {
JexlEngine JEXL = new Engine();
JexlContext jc = new MapContext();
JexlExpression e147 = JEXL.createExpression("quux = [one, two]");
jc.set("one", 1);
jc.set("two", 2);
int[] o1 = (int[])e147.evaluate(jc);
assertEquals(1, o1[0]);
assertEquals(2, o1[1]);
jc.set("one", 10);
jc.set("two", 20);
int[] o2 = (int[]) e147.evaluate(jc);
assertEquals(10, o2[0]);
assertEquals(20, o2[1]);
}
{code}

> Key: JEXL-147
> URL: https://issues.apache.org/jira/browse/JEXL-147
> Project: Commons JEXL
> Issue Type: Bug
> Affects Versions: 2.0.1
> Reporter: Marcel Schoen
> Priority: Minor
>
> Suppose there are two integer variables 'one' (with value 1) and 'two' (with
> value 2). Now I create an array variable with this expression:
> myArray = [ one, two ]
> Now I change the values of these variables later ('one' to 5 and 'two' to 6),
> and evaluate the same expression again:
> myArray = [ one, two ]
> Now I would expect "myArray" to be created again, this time with values 5 and
> 6. However, the second time, nothing really happens. Internally, "myArray"
> remains the same array from the first invocation (same Java String array
> object instance), with the same values (1 and 2). But since I was using
> variables with different values in the expression, I would expect the array
> to change / be re-created.
