[kepler-users] Question about the Display actor and the composite "class"

Hi,

I have following case:

1. I'm generating the Composite, putting just in and out port

2. Inside composite I'm connecting in and out,

3. I'm saving that composite to xml (so only the internal part of 
composite) to place on the Kepler path

4. I'm editing the xml file and changing the "entity" to "class" for the 
composite. That way as you know I can use that composite in many place,
and the changes would be applied to all the instances.

5. I can use that actor in the workflows , I can edit and add there inside 
most of the actors including other composite, and it works

6. The only problem I have so far is with the Display Actor:

When I try to add it to such created composite I'm getting error that is 
pasted below

I know maybe it is not standard way but, maybe you will know how to solve 
that problem, or what is the reason for that

thanks in advance

regards

Marcin
