passing Dictionary to Keyword with List argument creates ClassCastException

[hleskien]

Hi,

tested with Javalib-Core 2.0.3:

Java-Library:

    @RobotKeyword("Fügt eine neue Zeile mit den Werten der Liste ``values`` hinzu und gibt ihre y-Koordinate zurück.\r\n" +
            "\r\n" +
            "Beispiel:\r\n" +
            "| @{row}= | Create List | 1 | 2 | 3 |\r\n" +
            "| ${y}= | Add Row | ${row} |")
    @ArgumentNames({"values"})
    public int addRow(List<Object> values) {
        [...]
    }

Robot-Test:

    &{dict}=    Create Dictionary
    Add Row    ${dict}

Result:

I would expect a robot error message which says that one has used the wrong argument type.

Thank you and kind regards

I tried to reproduce this for further investigation and got a slightly different error:

java.lang.IllegalArgumentException: argument type mismatch

I don't know why it is different this time but I checked that I tested with Javalib-Core 2.0.3. Anyways, "argument type mismatch" is better than ClassCastException, but still not a robot AttributeError.
