I am trying to save a complete Teneo hosted resource using the
EcoreUtil.Copier class. When I call copier.copyReferences() I get the
following exception... I want to export to XMI/XML any ideas.?
Exception in thread "main" java.lang.NullPointerException

Put a conditional breakpoint at the location of the NPE and check the type of the owner and the
efeature.

Mark,
It should be something ending on IDX in the child table (or join table) with the name of the eclass
and efeature of the collection as a prefix.

Mark,
Yes, this case (of holes in the index) can occur in the following case:
Assume a type A which has a list of B's (non-containment and uni-directional association). In a
relational db this can be modeled using a join table between A and B or by using foreign-keys in the
B-table (pointing to A). In the latter case you loose referential constraint checking (on db-level)
when removing B (this is a symptom of the fact that references in a relational db can be directed
the other way than in java).
Let me illustrate this with an example: if an instance A1 has three B's: B0, B1, B2 (on indexes 0, 1
and 2 in the list). Then when I store A1 there will be one record in table-A and three records in
the B-table with an index column with values 0, 1 and 2 and a foreign-key column to the one A
record. Now to re-produce the exception you are getting: start a transaction and query for the B
objects (without reading A) and remove B1. What happens is that the B1 record is removed from the B
table. Commit the transaction. In the B-table two records remain with indexes 0 and 2. Begin a new
transaction then read A and open the list of B's. This will read B0 in index position 0 in the list
and B2 in index position 2 in the list. So index 1 stays empty and leaves a null value in the list.
There are different ways to handle this:
- Don't use list's on db level, so map lists (for which the above can occur) as bags (can be done
using an annotation).
- Perform programmatic referential checking before removing an object (the datastore has a
getCrossReferencers method to facilitate this)

In my version of emf, line 303 is this:
return eObject.eIsProxy() ? owner.eResolveProxy((InternalEObject)eObject) : eObject;
Can you see which is null eObject or owner?

Ok, then can you check the contents of the database to see if the index number of this collection
has any 'holes' (so there are records with index number 1,2,3 and then 5 and 6 for example).

Put a conditional breakpoint at the location of the NPE and check the type of the owner and the
efeature.

Martin,
OK, I have written a small routine to 'walk' through all the objects and
that way I found the offending collection. So, what is the column name
of the index I need to look for holes in pls.?

Mark,
It should be something ending on IDX in the child table (or join table) with the name of the eclass
and efeature of the collection as a prefix.

Martin,
I was able to resolve the original issue by finding the offending row in
the database and deleting...however, now I am getting a similar
exception later in the copy process. The stack is

Mark,
Yes, this case (of holes in the index) can occur in the following case:
Assume a type A which has a list of B's (non-containment and uni-directional association). In a
relational db this can be modeled using a join table between A and B or by using foreign-keys in the
B-table (pointing to A). In the latter case you loose referential constraint checking (on db-level)
when removing B (this is a symptom of the fact that references in a relational db can be directed
the other way than in java).
Let me illustrate this with an example: if an instance A1 has three B's: B0, B1, B2 (on indexes 0, 1
and 2 in the list). Then when I store A1 there will be one record in table-A and three records in
the B-table with an index column with values 0, 1 and 2 and a foreign-key column to the one A
record. Now to re-produce the exception you are getting: start a transaction and query for the B
objects (without reading A) and remove B1. What happens is that the B1 record is removed from the B
table. Commit the transaction. In the B-table two records remain with indexes 0 and 2. Begin a new
transaction then read A and open the list of B's. This will read B0 in index position 0 in the list
and B2 in index position 2 in the list. So index 1 stays empty and leaves a null value in the list.
There are different ways to handle this:
- Don't use list's on db level, so map lists (for which the above can occur) as bags (can be done
using an annotation).
- Perform programmatic referential checking before removing an object (the datastore has a
getCrossReferencers method to facilitate this)
