[jboss-user] [jBPM] - jBPM Eclipse modeler: How to enter a numerical value to a service node input parameter

whabelitz [https://community.jboss.org/people/whabelitz] created the discussion "jBPM Eclipse modeler: How to enter a numerical value to a service node input parameter" To view the discussion, visit: https://community.jboss.org/message/726870#726870 -------------------------------------------------------------- I #####use jBPM 5.0 and want to apply domain-specific service nodes with parameters of type Integer. So I define for the Eclipse process modeler something like [      "name" : "TestNode",      "parameters" : [          "stringPara": new StringDataType(),          "intPara" : new IntegerDataType(),      ],      "results" : [          "intResult" : new IntegerDataType(),      ],      "displayName" : "Test activity",      "icon" : "icons/action.gif" ] in my WorkDefinitions.conf file. How can I now enter integer values inside the process modeler when using such a service node? If I just enter a numerical value inside the property pane, I get an error (ClassCastException: java.lang.String cannot be cast to java.lang.Integer) after saving and reopening the process definition. The expression inside the process definition looks like       <dataInputAssociation>         <targetRef>_2_intParaInput</targetRef>         <assignment>           <from xsi:type="tFormalExpression">1</from>           <to xsi:type="tFormalExpression">_2_intParaInput</to>         </assignment>       </dataInputAssociation> If no solution for Eclipse is available, can the web modeler (Oryx Designer) handle numerical parameters?  And can the web modeler be used standalone (without Guvnor) reading and writing process definitions from/to the file system? If I manage to handle numerical values during process design, what is during runtime? Can I access this parameter inside a WorkItemHandler using "(Integer) workItem.getParameter("intPara")" or will this cause a class cast exception? My work around at the moment is defining non string values inside a script node and using parameter mapping, but this is not a nice solution and inflate the process definition -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/726870#726870] Start a new discussion in jBPM at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&...]
