I do try to help other when i can, but find myself stuck on a few items here.
In my AlertDto, I have these 2 methods:
public void setRemovedContacts(Collection removedContacts)
{
this.removedContacts.clear();
this.removedContacts.addAll(removedContacts);
} public void clearContacts()
{
this.Contacts.clear();
}I am just looking now for which ones I am using as I have started other things while waiting for responses.

Mick,
I'm not using Vos nor modeled M:N relationships (I need attributes on the joining table), but I took a look at the generated VO code (it's still in there, I'm just not using it). It seems pretty clear that what your doing will not work without modifying the generated VO-code (the template, really).
Here's what happens when you remove a Phone from a User (User is 1:N to Phone):
public void removePhones(dd.ejb.entity.identity.PhoneVO removed) { this.Phoness.remove(removed); this.removedPhoness.add(removed); if (this.addedPhoness.contains(removed)) this.addedPhoness.remove(removed); if (this.updatedPhoness.contains(removed)) this.updatedPhoness.remove(removed); }
Ignore the fact that Phones are called Phoness (I named the aggregate Phones as the example code uses plural too). It stores a reference in the "to-be-removed" collection. However, here's the code for clearing the list of Phones:
public void clearPhoness() { this.Phoness.clear(); }
As you can see, it just "forgets" the loaded phones. It doesn't put them into the "to-be-removed" collection to be used by the bean. This should loop through the phones and call removePhone() for each. I suggest you look at the generated VO code for you M:N relationship and see if it's doing something similar.
On a personal note, please remember that this is not a support forum. I do not work on Xdoclet (though I'd like to find some small piece to help out with) -- I'm a user like you. I help others out when I can for many reasons: it improves my knowledge, it's good karma, and finally, I'm just a nice guy. :) It doesn't inspire me to help when I read, "is there just no person ... willing to help?" I guess my only suggestion would be to try to investigate the issue further if you get no response rather than reposting the same query with no additional information again and again. </soapbox>
Good luck!

P.S. Was my reply about your 1:1 relationship issue helpful? Did you get anywhere with it?

Am I the only person trying to delete the 'n' side of m-n relationships? or is there just no person in the past 3 weeks of my asking willing to help me fix this issue? Can someone please help?
I can't seem to figure out how to delete the m-n relationships. I can create them just fine, but when I try to call clear() on my VO, the values do not sem to get cleared, and they are not deleted from the relation table.
