NodeMappingImport loses bordered nodes of imported node [message #1719939] Wed, 13 January 2016 11:11 Go to next message

Hi,

I am trying to understand the Sirius Documentation, more specifically
the section on node mapping imports:

https://www.eclipse.org/sirius/doc/specifier/diagrams/Diagrams.html#diagram_extension

I have attached an example that's based on the sample family model from
sirius:

I added two additional classes Wallet and Lover, and two new containment
references to the Man class: wallet, lovers.

I then added a BorderedNode to the existing Man mapping, so that a Man's
wallet is displayed as a BorderedNode in a family diagram. This works fine.

I now add a Diagram Extension that defines an additional layer which
should also display a Man's lover as a bordered node. To do so, I create
a NodeMappingImport which imports the original Man mapping. I then add a
new BorderedNodeMapping child that will create bordered nodes for a
man's lover.

Now, from the documentation I understand that if I enable the extension
layer, a Man should display both, bordered nodes for wallets, and
bordered nodes for lovers. What happens however is that when I enable
the extension layer, the lovers nodes appear but the wallets nodes
disappear. If this is expected behaviour, then the documentation is
quite misleading.

Thanks for comments,
Felix

Hi Felix,

By default the sub-nodes of an imported mapping are not displayed. You
need to explicitly add the border node you want to reuse in "Reused
Bordered Node Mappings" in the "Import" tab.

I see. So if I am the maintainer of an extension like that, I have to
continuously monitor the extended .odesign files for additions/removals
of its child bordered nodes, or I risk that my extension doesn't show
nodes that have been newly added, or also that my extension shows nodes
that have been removed.

So I have this crazy idea to avoid this problem, maybe you have
comments: Shouldn't it be possible that I 'fix' my extension dynamically
at runtime by updating its mapping model so that it always reuses
exactly the bordered nodes of the imported mapping plus my own added
borded node.

I agree with that. Ideally, the specifier should have the possibility to
add all imported mapping sub-node by default. That sounds like a good
feature request.

It is a possibility. But you have to make sure the VSM model is properly
updated before opening any representation to avoid a refresh with the
"old" VSM.

You mean in the specifier editor? That would save some time, but still
keep the maintenance burden, since the imported mapping might change
over time.

I will have a look, but IIRC the ViewpointRegistry API will give me a
hard time to transform/update a VSM model before it's registered (or used..)
