We are having a lot of troubles with the ecore diagrams. We are using them
heavily as they are so useful - i.e. we use them almost exclusively to
develop our models.

Unfortuately they are extremely brittle. Our model is evolving heavily and
we keep breaking the diagrams. The worst part is not simply that they
break but that they break leaving no clue as to how to fix it. This is
because we tend to get these NPE's. If this was trapped and a useful
message given then we could modify the xml for the diagram and fix the
problem (in theory at least).

This would be very valuable until such a time as proper refactoring
support is built into the diagrams.

Is there any advice as to how to determine the cause of breaks such as
these?

Also, how long before we have a way to evolve the ecore models that
doesn't break the diagrams?

The NPE is

java.lang.NullPointerException

Hi Andrew,

Can you please open a bug [1] against EcoreTools with your NPE's stack
trace (and, if possible, steps to reproduce)?

Thanks!
Benjamin

Hi Benjamin

I've created a couple more feature requests that would make our life
easier.

We have a single model for our domain model, but due to its size we
realised it is impractical to keep it in one ecore file (due to
performance).

So we broke it up into many ecore files (mostly one file per package)
using the <eSubpackages href="sub.ecore#/"/> feature. Its still logically
the same, but physically its not. We want to work with it though as if it
were just one file.

The first request is to add support for the <eSubpackages
href="sub.ecore#/"/> feature in the editor.
The second is for improving how ecore diagrams work with such an approach.

Hi Benjamin

I've created a couple more feature requests that would make our life
easier.

We have a single model for our domain model, but due to its size we
realised it is impractical to keep it in one ecore file (due to
performance).

So we broke it up into many ecore files (mostly one file per package)
using the <eSubpackages href="sub.ecore#/"/> feature. Its still logically
the same, but physically its not. We want to work with it though as if it
were just one file.

The first request is to add support for the <eSubpackages
href="sub.ecore#/"/> feature in the editor.
The second is for improving how ecore diagrams work with such an approach.
