[kepler-dev] MultiInstanceComposite - two issues

[Michal Owsiak]

Hello Kepler team,

I have two issues with Multi Instance Composite actor.

What I am trying to achieve is embedding DDF workflow within PN workflow 
where internal composite actor (driven by DDF) is started in N multiple 
instances.

The workflow I am trying to embed is attached as SimpleLoop.kar

The workflow I am trying to build is attached as MultiInstance.kar

It looks pretty straightforward to build this workflow, however I have 
two issues:

1. When I build MultiInstance workflow from the scratch it doesn't work 
at all.

I have to close Kepler and reopen it to get workflow started.

2. Second issue is that workflow doesn't work properly if I put Display 
actor inside. There are issues while instantiating components.

You can validate this issue by opening MultipleInstance.kar and putting 
Display actor somewhere inside Composite actor (connect it to any 
relation inside).

I have two questions regarding Multi Instance Composition.

Question 1: do I have to make some assumptions regarding sub workflow 
when it comes to embedding workflow within Multi Instance Composite?

Question 2: is it possible to use Display actor within Multi Instance 
Composite. Is there any workaround?

Thanks in advance for the support

Cheers

Michal
