Henri Biestro created JEXL-136:
----------------------------------
Summary: Script calls within scripts may fail with number arguments
Key: JEXL-136
URL: https://issues.apache.org/jira/browse/JEXL-136
Project: Commons JEXL
Issue Type: Bug
Affects Versions: 2.1.1
Reporter: Henri Biestro
Assignee: Henri Biestro
Fix For: 2.1.2, 3.0
Jexl attempts to narrow arguments when solving function names; unfortunately,
this may cause issues when the function is a script and the argument type is
expected to remain untouched.
The map key in the following code is an Integer; by calling the function fn01,
the interpreter fails to find a method and retries after 'narrowing' the
argument which becomes a Byte. The Byte is not equal to the Integer map key
with the same value; the test fails.
{code}
@Test
public void test136() throws Exception {
JexlEngine jexl = new Engine();
JexlContext jc = new MapContext();
JexlScript script;
JexlExpression expr;
Object result;
script = jexl.createScript("var x = $TAB[idx]; return x;", "idx");
jc.set("fn01", script);
script = jexl.createScript("$TAB = { 1:11, 2:22, 3:33}; IDX=2;");
script.execute(jc);
expr = jexl.createExpression("fn01(IDX)");
result = expr.evaluate(jc);
assertEquals("EXPR01 result", 22, result);
}
{code}
