Dmitri Blinov commented on JEXL-270:
------------------------------------
Somehow the source text of the curried lambda in the second test case becomes
the one of the script itself, i.e. {{var base = 0; var sum = (y, z) ->
{var x = base; x += y; return x}; base = 2; var y = sum.curry(1); y.toString()
eq sum.toString()}}, not the \{{(y, z) -> {var x = base; x += y; return x}
}}, if this is of any help
> Wrong Script$Curried creation when script.curry() method is called inside

> Key: JEXL-270
> URL: https://issues.apache.org/jira/browse/JEXL-270
> Project: Commons JEXL
> Issue Type: Bug
> Affects Versions: 3.1
> Reporter: Dmitri Blinov
> Priority: Major
>
> I have noticed that when i call lambda.curry() method inside the script, then
> the curried lamba is created with wrong source text. I expect the source text
> of the curried lambda to be always equal to that of original, but that is not
> the case now. To illustrate this I have prepared two testcases, from which
> {{testCurryScript2}} fails with
> [ERROR] Failures:
> [ERROR] LambdaTest.testCurryScript2:307 expected:<true> but was:<false>
> {code:java}
> @Test
> public void testCurryScript() throws Exception {
> JexlEngine jexl = new Engine();
> JexlScript base = jexl.createScript("(x, y, z)->{ x + y + z }");
> String text = base.toString();
> JexlScript script = base.curry(5, 15);
> Assert.assertEquals(text, script.toString());
> JexlEvalContext ctxt = new JexlEvalContext();
> ctxt.set("s", base);
> script = jexl.createScript("return s");
> Object result = script.execute(ctxt);
> Assert.assertEquals(text, result.toString());
> script = jexl.createScript("return s.curry(1)");
> result = script.execute(ctxt);
> Assert.assertEquals(text, result.toString());
> }
> @Test
> public void testCurryScript2() throws Exception {
> JexlEngine jexl = new Engine();
> JexlScript base = jexl.createScript("var base = 0; var sum = (y, z)
> -> {var x = base; x += y; return x}; base = 2; var y = sum.curry(1);
> y.toString() eq sum.toString()");
> Object result = base.execute(null);
> Assert.assertEquals(Boolean.TRUE, result);
> }
> {code}
