----------------------------------
Summary: Hoisted variable is lost when currying lambda
Key: JEXL-271
URL: https://issues.apache.org/jira/browse/JEXL-271
Project: Commons JEXL
Issue Type: Bug
Affects Versions: 3.1
Reporter: Dmitri Blinov
I have noticed that when I curry the lambda that contains hoisted variable,
then binding to that variable is lost when I call curried lambda. The following
test case illustrates the problem
{code}
@Test
public void testCurry4() throws Exception {
JexlEngine jexl = new JexlBuilder().strict(false).create();
JexlScript base = jexl.createScript("var base = 2; var sum = (x, y,
z)->{ base + x + y + z }; var y = sum.curry(1); y(2,3)");
Object result = base.execute(null);
Assert.assertEquals(8, result);
}
{code}
To put it another way, the following script returns {{2}} when it should return
{{0}};
{code}var base = 2; var sum = (x, y, z)->{ base + x + y + z }; var y =
sum.curry(1); sum(1, 2, 3) - y(2,3){code}
