> Implicit type conversion fails in code gen

> This test fails. Many other implicit type conversions fail as well.
> {code:java}
> @Test public void testLongScalarNoCast() {
> tEnv.createTemporarySystemFunction("func", new GreetingLongScalar());
> tEnv.executeSql("CREATE VIEW Names(name) AS VALUES ('Bob'), ('Alice'),
> ('Bob')");
> final List<Row> results = executeSql("SELECT * FROM func(TABLE Names
> PARTITION BY name, 100)");
> final List<Row> expectedRows = Arrays.asList(
> Row.ofKind(RowKind.INSERT, "Bob", "Hello 100!"),
> Row.ofKind(RowKind.INSERT, "Alice", "Hello 100!"),
> Row.ofKind(RowKind.INSERT, "Bob", "Hello 100!"));
> assertThat(results).containsSequence(expectedRows);
> }
>
> /** A PTF that takes an int argument and returns a greeting. */
> public static class GreetingLongScalar extends ProcessTableFunction<String> {
> public void eval(
> @ArgumentHint(ArgumentTrait.SET_SEMANTIC_TABLE) Row input,
> long arg) {
> collect("Hello " + arg + "!");
> }
> }
> {code}
> The intended behavior is that if an implicit cast can be done without losing
> any precision, it should "just work". This is how other UDFs work as well.
