Hi Henrib,
please try it with code below.
The result is:
EXPR01 result=null ## NOT OK
EXPR02 result=22 ## OK
Is anywhere available built 3.0 SNAPSHOT jar file or do I need to build it
myself from SVN repository?
Best regards,
Tomas

Subject: Re: [jexl] Unexpected Integer -> Byte conversion
Hi Tomas,
Your previous issue (JEXL-135) has been solved in the trunk (2.1.2 and 3.0).
Not sure about this one, I can't reproduce it on the trunk using the
following test:
{code}
public void test135() throws Exception {
JexlEngine jexl = new JexlEngine();
JexlContext jc = new MapContext();
Script script;
Object result;
Map<Integer, Object> foo = new HashMap<Integer, Object>();
foo.put(3, 42);
jc.set("state", foo);
script = jexl.createScript("var y = state[3]; y");
result = script.execute(jc, foo);
assertEquals(42, result);
jc.set("a", 3);
script = jexl.createScript("var y = state[a]; y");
result = script.execute(jc, foo);
assertEquals(42, result);
jc.set("a", 2);
script = jexl.createScript("var y = state[a + 1]; y");
result = script.execute(jc, foo);
assertEquals(42, result);
jc.set("a", 2);
jc.set("b", 1);
script = jexl.createScript("var y = state[a + b]; y");
result = script.execute(jc, foo);
assertEquals(42, result);
script = jexl.createScript("var y = state[3]; y", "state");
result = script.execute(null, foo, 3);
assertEquals(42, result);
script = jexl.createScript("var y = state[a]; y", "state", "a");
result = script.execute(null, foo, 3);
assertEquals(42, result);
script = jexl.createScript("var y = state[a + 1]; y", "state", "a");
result = script.execute(null, foo, 2);
assertEquals(42, result);
script = jexl.createScript("var y = state[a + b]; y", "state", "a",
"b");
result = script.execute(null, foo, 2, 1);
assertEquals(42, result);
}
{code}
Let me know what I'm missing.
Regards
Henrib
PS: If you are starting/evaluating to use JEXL and if you can, I'd suggest
you use the 3.0 SNAPSHOT (published a new one today).
