Hi,
I'm using Drools commands API
(http://downloads.jboss.com/drools/docs/5.1.1.34858.FINAL/drools-integration/html_single/index.html#d0e614)
for interacting via REST to my Drools server for executing flows.
I want to execute a simple flow with some human tasks. In this flow, I'm
passing a client object which will be modified inside the flow in script
nodes (client.setParameter("parameterChanged");)
The code i'm using for executing this flow is below:
Command insertObjectCommand = CommandFactory.newInsert(client,
"client", true, null);
Map<String, Object> params = new HashMap<String, Object>();
params.put("client", client);
WorkItemHandler htHandler = new WSHumanTaskHandler();
List<Command> cmds = new ArrayList<Command>();
RegisterWorkItemHandlerCommand workItemHandlerCommand = new
RegisterWorkItemHandlerCommand(
"Human Task", htHandler);
StartProcessCommand startProcessCommand = new
StartProcessCommand();
cmds.add(insertObjectCommand);
startProcessCommand.setProcessId("harrods.HumanFlow");
startProcessCommand.setParameters(params);
cmds.add(workItemHandlerCommand);
cmds.add(startProcessCommand);
result = execute(cmds); //Execute is a function which takes
care of
marshalling commands and sending them to the execution server.
This starts the process correctly, i can complete the user tasks correctly
(i see in traces that the object is modifyed), but the problem is that i
can't retrieve the modified object from my application.
I try to do this from my application:
FactHandle fact = (FactHandle) result.getFactHandle("client");
cmds.clear();
GetObjectCommand getObjectCommand = new GetObjectCommand(fact);
getObjectCommand.setOutIdentifier("client");
cmds.add(getObjectCommand);
result = execute(cmds);
But i'm obtaining the same object i sent to the flow (without the flow
modifications).
So, the question is, how can i modify objects inside my flow and retrieve
them in my application using drools commands api?? is it possible? i'm doing
something wrong?
I have the same example without execution server using normal API, and it
works fine...
Some ideas?
Thanks
