Code Generation on self referential aggregation

[nifsmith]

Generating code from EA for a class aggregating itself (having set ArrayList as the default collection for C#) within EA does not generate code to include an ArrayList to hold the self reference.

The code generator will however create an ArrayList to hold a collection if the aggregation is between two different classes.

Also I don't seen to be able to alter (bend line at cursor) or stretch a self referential link to fit.

 Sounds like a problem I'm having myself, could you expand a bit more.

Now now, young bruce, you know it should be an:

I'll expand on the code generation issue.

Currently a self-aggregation drawn in the default way will not generate an attribute at all.  There is a fix for this coming, but I don't expect it to come until build 788.

There are a couple of workarounds to the issue that I've found.  

1. Use an association without setting the aggregation on either end.
2. Here's the devious one,   Swap the information in the source role and target role.  I'm guessing that nifsmith's link has the following properties.

Source Role:
- Multiplicity 0..*
- Aggregation none
Target Role:
- Aggregation shared

If you change that to the following it should work as you expect.

Source Role:
- Aggregation shared
Target Role:
- Multiplicity 0..*
- Aggregation none
