Description
When tasks input/output is retrieved using the API - it doesn't include the actual values, but only data types.
See attachment eD2h.png for a sample human task configured.
This is the script I have used for retrieving input mapping values:
System.out.println("before everything"); if ( kcontext.getNodeInstance() instanceof org.jbpm.workflow.instance.node.HumanTaskNodeInstance) { System.out.println("inside if"); org.jbpm.workflow.instance.node.HumanTaskNodeInstance y = (org.jbpm.workflow.instance.node.HumanTaskNodeInstance) kcontext.getNodeInstance(); org.jbpm.workflow.core.node.HumanTaskNode x = y.getHumanTaskNode(); System.out.println("ht node keyset size:"+x.getMetaData().keySet().size()); for (java.util.Map.Entry<String, String> in : ((java.util.Map<String, String>) x.getMetaData("DataInputs")).entrySet()) { System.out.println("input key:"+in.getKey()+", input value:"+in.getValue()+", in value class:"+in.getValue().getClass()+", in value tostring:"+in.getValue().toString()); }} }
And this is the output I've got:
10:54:46,339 INFO [stdout] (http-127.0.0.1:8080-7) before everything 10:54:46,339 INFO [stdout] (http-127.0.0.1:8080-7) inside if 10:54:46,339 INFO [stdout] (http-127.0.0.1:8080-7) ht node keyset size:9 10:54:46,339 INFO [stdout] (http-127.0.0.1:8080-7) input key:Skippable, input value:Object, in value class:class java.lang.String, in value tostring:Object 10:54:46,339 INFO [stdout] (http-127.0.0.1:8080-7) input key:Description, input value:java.lang.String, in value class:class java.lang.String, in value tostring:java.lang.String 10:54:46,339 INFO [stdout] (http-127.0.0.1:8080-7) input key:CreatedBy, input value:java.lang.String, in value class:class java.lang.String, in value tostring:java.lang.String 10:54:46,339 INFO [stdout] (http-127.0.0.1:8080-7) input key:TaskName, input value:String, in value class:class java.lang.String, in value tostring:String 10:54:46,339 INFO [stdout] (http-127.0.0.1:8080-7) input key:Content, input value:java.lang.String, in value class:class java.lang.String, in value tostring:java.lang.String
As you can see instead of seeing Skippable - true, I see Skippable-Object.
This has wider impact, because also jBPM services, which are consequently used in Kie Server uses this API.
If I try to retrieve the task details for the same task when attached, via kie-server rest api, this is the result:
<user-task-definitions> <task> <task-name>test</task-name> <task-priority>0</task-priority> <task-created-by>java.lang.String</task-created-by> <task-skippable>false</task-skippable> <associated-entities> <associatedEntities>anton</associatedEntities> </associated-entities> <task-inputs> <entry> <key>Description</key> <value>java.lang.String</value> </entry> <entry> <key>CreatedBy</key> <value>java.lang.String</value> </entry> <entry> <key>TaskName</key> <value>String</value> </entry> <entry> <key>Content</key> <value>java.lang.String</value> </entry> <entry> <key>Skippable</key> <value>Object</value> </entry> </task-inputs> <task-outputs/> </task> </user-task-definitions>
Another consequence is that Skippable will be always set to false, because this call
https://github.com/droolsjbpm/jbpm/blob/738d191d338dab3e8baceeaf6fe31556b81fe07f/jbpm-services/jbpm-kie-services/src/main/java/org/jbpm/kie/services/impl/xml/ServicesProcessDataEventListener.java#L98
Will have these values:
task.setSkippable("true".equalsIgnoreCase("Object"));
And that will always result to false
