Rational Apex imports

Rational Apex imports

[amendola9343]

     Hello,

     I am trying to learn the Rational Ada environment. I'm having problems
with imports. I am trying to import two views from one subsystem into another,
and Rational only want's to let me import one. Is it possible to import two?

You need to do a mutial import.

No, that won't work.  Mutual imports only work if they are views of
different subsystems.

The earlier response was correct... you cannot import two views of
the same subsystem.

You're right -- I read the post too quickly, and thought he was talking
about two subsystems.  Sorry.

Perhaps some explaination is in order... In Rationalese a subsystem is a set 
of objects, and a view is a version of those objects... If you try and import 
two views from the same subsystem, then Rational things you are trying to 
import two version of the same objects, thus it won't let you...

This seems confusing as you may have different objects in the views, but at 
some point you have to check them in, and then things get weird...

Have no fear create more subsystems...

Nope.  You can't do that 'cause it has the potential to cause all sorts
of naming conflicts.  

If you have separate sets of files, keep them in separate subsystems. 
Then you can import two views since they are in different subsystems.

Hope this helps.

Rational Subsystems correspond to logical "chunks" of your application. 
The subsystem views represent exactly that, ie, views into the
subsystem.  On many projects, the views represent snapshots of the
development of the subsystem (eg, older views are older versions of the
subsystem, later views are later versions).  Views are also used to
support team development, eg, each developer can have his/her own view
to use as a "play area" where changes can be made without fear of
negative impacts on the other developers.

When building your application, many subsystems may be linked together,
but only one view from each subsystem may be used.  If you think about
it, trying to link multiple views from the same subsystem into an
application is like saying you want two versions of the same source file
compiled and included in your application -- that's normally not a good
thing to do (to put it nicely :-).  You should contact your local
Rational representative or send email to me (make the obvious fix to my
email address) and we can discuss this further.
