Unable to start process via GP API in which group is exposed as input

[Former Member]

Hi,

I am not been able to start process using GP API for the particular senario.

I created Process at design time.

In this process I mapped parameters to a group and exposed this group, So that input is required for initiating the process.

Now I want to initiate this process via GP API.

I got sucess in starting processes which takes parameters as inputs or which does not need any inputs, but i was not been able to start process where group is exposed.

it's giving me GP INVOCATION Exception.

Please Help ASAP

Regards,

Pratik,

I try to simulate with scenario described by you and I got success with my test.

Follow my java code:

	public boolean initiateProcessSDN () { 
		boolean ret = false;
		try {
		
			IUser user = UMFactory.getUserFactory().getUserByLogonID("uces");
			IGPUserContext userContext = GPContextFactory.getContextManager().createUserContext(user);
			IGPProcess processTemplate 
				= GPProcessFactory.getDesigntimeManager().getActiveTemplate(
						"8DC0B411957D11DDB7910017F2EBE4A5", userContext);
			
			IGPRuntimeManager rtm = GPProcessFactory.getRuntimeManager();
			IGPStructure params	= GPStructureFactory.getStructure(processTemplate.getInputParameters());
				
			params.setAttributeValue("NameGroup", "Pedro");
			params.setAttributeValue("AddressGroup", "XPTO");
			
			IGPProcessRoleInstanceList roles = rtm.createProcessRoleInstanceList();
			
			IGPProcessInstance prInstance 
				= rtm.startProcess(	processTemplate, 
								"Test 1", 
								"Test 2",
								user, 
								roles, 
								params, 
								user);
			ret = true;
			} catch (Exception ex) {
				ret = false;
			}
		return ret;
	}
