BUG: XMI Import Multiplicity (0..*) Lost

[dykebert]

Hi there,
I'm currently evalutating EA for our business.

When I import XMI (1.1 or 1.2) the Associations import correctly but ALL 0..* multiplicity is lost.  This is true when the XMI is generated from another tool as well.

When I import XMI 1.0 generated by EA the 0..* is imported correctly.

I haven't tried all multiplicities, but 0..1, 1..1, and 1..* import just fine.  It's only 0..* in XMI 1.1 or 1.2.

Looking forward to a fix.

Thanx,

Hi,

Currently you can export and import a 0..* labelled multiplicity from an EA model to an EA model using XMI 1.1.  I have confirmed this with tests here, so if you have a situation where this does not occur I would be very interested to know about it.

However when importing from other tools, or using XMI 1.2, you can only explicitly import 0..* if that association end has a rolename specified.  However if no multiplicity is explicitly specified, then 0..* is the default in EA anyway.

To summarise: While not shown, the multiplicity is still set correctly. It will not be shown on the diagram unless you also specify the role of the association end.

Thanx for the quick reply.  

I finally found some time to run some more tests.

And yes when I name the role, the 0..* multiplicity is correctly labled after import

You said that 0..* is the default. However when I generate a Schema from the imported model 0..1 is implemented.  If the multiplicity is explicity set to 0..* then the Schema is 0..* as well.

While creating different scenarios I noticed two other issues.

1. Multiplicty of 1 is set to 0..1 during XMI 1.2 export

2. If the association has a name, the name is dropped on import.

Again all of this is EA to EA using XMI 1.2 on the export.

I've put this together in a MS Word doc that includes the graphics and the XMI. If you're interested message me with an e-mail address and I'll send it to you.

Thanx,
Sharky
