Merge packages or models

[stirling]

Hello,

I just wonder if anyone has tried 'Package Merge', and had figured how this thing should work.  For me, there is no effect at all as to either of the target or source packge.  The 'merged effect' is nowhere to be seen.
Another question: Is it possible to merge two models?

Thanks.

I've tried that some time back in 9.3 but was not happy with the results. So I dropped further attempts.

Regarding merge of projects: I'd say you can "merge" two components of a soft drink to create something new. But merging two projects will simply result in non-sense. What you can do is to import parts via package XMI ex-/import.

You're right.  It does not make sense to merge two projects but packages or models internal to a same project 'should' be possible. Otherwise, it's a pain to copy and paste, and in some case re-add all the elements.

I'm guessing that the case you're looking at is that you have had two (or more) independent modelers, and now want to combine their work. As a result you're wanting the package merge to match elements based on their names. Unfortunately, the feature only works with the unique ids that will never¹ match for two independently created elements.

¹ Assuming perfect random number generation and every EA license creating elements flat out for a lifetime there would be a tiny chance. But the chance of it being two modelers interpretation of the same thing is not measurably different from zero.

Hi, Simon,
In this project, I have two packages with one model each.
I am the only modeler creator of both.
Merging the same packages does not do anything. The functionality doesn't work.  Or, if it does, it's not obvious.
What would be the result of the merge, visually on the diagram or in the merged package?  Is the merge working at all in version 9?  Should I upgrade to version 10?
Thanks.

It works as designed, but I still expect you're trying to compare based on names only.

Try exporting both packages to XMI. The compare is only intended to operate if the guids (xmi:id) are the same in both.
