<div class="jive-rendered-content"><p>Hi,</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>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().</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>For example, let me share one definition that is causing me fits:</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>[</p><p>        "name" : "SFTPget",</p><p>        "parameters" : [</p><p>            "Host Name" : new StringDataType(),</p><p>            "User Name" : new StringDataType(),</p><p>            "Password" : new StringDataType(),</p><p>            "File Location" : new StringDataType(),</p><p>            "File Name" : new StringDataType(),</p><p>            "Target Directory" : new StringDataType(),</p><p>            "Delete Original" : new StringDataType(),</p><p>            "Log Level" : new StringDataType(),</p><p>            "Date Format" : new StringDataType(),</p><p>            "Date Format to lowercase" : new StringDataType(),</p><p>            "Date Format Offset" : new IntegerDataType(),</p><p>            "Reply Timeout": new IntegerDataType()</p><p>        ],</p><p>        "displayName" : "sFTP Get",</p><p>        "icon" : "icons/computer_world.gif"</p><p>    ]</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>In the WorkItemHandler, I have the following code that worked prior to upgrading, but now throws ClassCastException:</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>Integer dateOffset = (Integer) ((workItem.getParameter("Date Format Offset") == null)? 0: workItem.getParameter("Date Format Offset"));</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>The object returned by workItem.getParameter("Date Format Offset") is a String.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>My questions would be as follows:</p><p>1. Is this just the way jBPM 5.3 works, and am I to manually cast all parameters from String to the desired type?</p><p>2. If #1 is no, then is this a bug or something I need to change in my code?</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>Thanks for the help/tips!</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>-Paul</p></div>
