I am looking for a possibility to implement a serviceTask which should be able to create objects with arbitrary properties. I would like to have these properties injected as Map into my serviceTask expression.For example I want to define this in my process definition like:<serviceTask id="javaService" name="Java service invocation" activiti:class="org.activiti.examples.bpmn.servicetask.CreateObject"> <activiti:field name="objectType" stringValue="dummy"/> <activiti:field name="properties"> <activiti:map> <activiti:entry key="key0"><activiti:string>Hello World</activiti:string></activiti:entry> <activiti:entry key="key1"><activiti:expression>Hello ${gender == 'male' ? 'Mr.' : 'Mrs.'} ${name}</activiti:expression></activiti:entry> </activiti:map> </activiti:field></serviceTask>
My service task implementation would be like this:public class CreateObject implements JavaDelegate { … private Expression objectType; private Expression properties; public void execute(DelegateExecution execution) { String type = (String) objectType.getValue(execution); Map props = (Map)properties.getValue(execution); myRepository.addNode(type, props); }}…
As far as I know, currently only activiti:string and activiti:expression are supported. Are there any plans for supporting such a serviceTask field type. Or should I use a different implementation strategy?
