Matrix View

[didier]

When re-selecting the same criteria in the Relationships Matrix, EA is not showing the relationships i created earlier (the relationships are correctly created since i see them appearing on another diagram and in the generated html documentation)

In fact when starting the matrix it is always empty (no relationships displayed)

Is this the normal behavior ?

Didier,
it depends on what you want to show. You must select source and target package (this can be either the whole project) the type of elements and the type of relation (directional or unspecific). Once you set up the matrix you can give the settings a name (e.g. Use Case vs. Requirements). You can then reload from the named settings.

(this was my 1000'th post - skoal :-))

Thomas,
I'm doing what you explained (I suppose you mean the "refresh" button with "reload") ; even with the whole project the matrix is always empty ...

KIPPIS, ANDREW (17251795) , English nonconformist divine and biographer, son of Robert Kippis, a silk-hosier, was born at Nottingham on the 28th of March 1725

(I guess it's something cryptic regarding my 1000'th post)

Okay,  I guess, we have to do it step by step. To repeat my Requirements/Use Case example:
- create a package with a use case, a requirement and a diagram. Draw a realize relation from the use case to the requirement.
- open the matrix
- click Source. You should see a project browser. Select the newly created package.  
- Go to the Type drop down right of source and select Use Case as element type.
- Repeat the procedure with Target, but Requirements as element type. Now you have a matrix with Use Cases against Requiremets..
- select the type Realisation for relation.
- select Target->Source from direction.

You now should see a cross in the matrix. You can select that cross and from the context menu delete the relation. If you now switch to the diagram, you see that the relation has vanished. Back to the matrix you can re-create it by selecting the entry and creating it via the context menu.

Thx Thomas !
I was not selecting the Target since the matrix was designed as i expected (but without the crosses)
Why is that field not mandatory ? It is grayed out as if it was an unimportant field
Anyway Thx again

[thomaskilian]

Both source and target are mandatory. A matrix with 0 columns and/or rows is still valid, although quite meaningless

Kippis !

Hi Mike,
PLEASE give me an explanation since surely you did not mean Mr. Kippis, did you?

[mikewhit]

It's the Finnish (suomi) equivalent of 'skoal'/skol .
With a slightly different literal meaning, I believe.

Aim thin skoal / Main skoal hit / Aint skoal him (which are anagrams of my name). I should have improved my Finnish

Edit: this was post 2**10 or 1k or 1024; maybe 2**9 of my posts were just silly
