V9 and v12 MDG rendering behaviour differs

[Paolo F Cantoni]

We use both V12 to our manual modelling and we often use v9 (909) to do automated stuff (since it's up to 10 times faster than later builds).

We tend to add stuff via v12.  However, we've observed that if we view V12 created objects with v9, they don't apply the background colour etc...
<Stereotype name="ArchiMate_Product" metatype="Product" notes="" bgcolor="10092543" fontcolor="0" bordercolor="0" borderwidth="1" hideicon="0">

We put this down to the fact that in v9, when you create an item from the MDG, it (incorrectly) sets the Default Appearance... ([F4]), whereas in V12 it (correctly) sets the rendering attributes as though from the shapescript - that is, "on the fly".

Have we understood the differences in behaviour correctly?  We need to understand this to know what to do with historical (pre-changeover objects).

TIA,
Paolo

Yes.

In EA 9 the stereotype color is set to the element default color at creation.
In EA 12 the stereotype color is used if no default color has been set.

EA 9 objects will render the same in 12. The reverse is never guaranteed.
