Hi,

I am in the process of upgrading from Drools 5.0 rule flows to jBPM 5.3 BPMN processes.  All is going well for the most part, but I ran into an odd snag.  I have 25+ WorkItemHandler's defined.  Several of them use IntegerDataType's for input parameters.  Now, in jBPM 5.3, all parameters seem to be passed to the hander as String, regardless if it's defined as a type other than StringDataType().

For example, let me share one definition that is causing me fits:

[
        "name" : "SFTPget",
        "parameters" : [
            "Host Name" : new StringDataType(),
            "User Name" : new StringDataType(),
            "Password" : new StringDataType(),
            "File Location" : new StringDataType(),
            "File Name" : new StringDataType(),
            "Target Directory" : new StringDataType(),
            "Delete Original" : new StringDataType(),
            "Log Level" : new StringDataType(),
            "Date Format" : new StringDataType(),
            "Date Format to lowercase" : new StringDataType(),
            "Date Format Offset" : new IntegerDataType(),
            "Reply Timeout": new IntegerDataType()
        ],
        "displayName" : "sFTP Get",
        "icon" : "icons/computer_world.gif"
    ]



In the WorkItemHandler, I have the following code that worked prior to upgrading, but now throws ClassCastException:

Integer dateOffset = (Integer) ((workItem.getParameter("Date Format Offset") == null)? 0: workItem.getParameter("Date Format Offset"));


The object returned by workItem.getParameter("Date Format Offset") is a String.


My questions would be as follows:
1. Is this just the way jBPM 5.3 works, and am I to manually cast all parameters from String to the desired type?
2. If #1 is no, then is this a bug or something I need to change in my code?

Thanks for the help/tips!

-Paul
