Re: No object is registered in context with Id

Change the line that throws the exception --> newItem.setContact(item);
to:  newItem.setContact( getObjectContext().localObject( item ) );

Here's the rest of the stack.

The reason I was setting all the objects to use the same ObjectContext
was that the objects themselves are setup in multiple threads and I was
getting ObjectContext errors.

Here is the error I was trying to get around.

Using this code...

                ObjectContext oc = UI.getObjectContext();
                int addItemCount = 0;
                for (Contact item : list) {

                    ProjectContact newItem =
oc.newObject(ProjectContact.class);

                    //project.setObjectContext(oc);
                    //project.getCompany().setObjectContext(oc);
                    newItem.setCompany(project.getCompany());
                    //item.setObjectContext(oc);

exception-->newItem.setContact(item);
                    newItem.setProject(project);
newItem.setPrimeContact(ProjectContact.Type.NON_PRIME.getCode());
                    addItemCount++;
                }
            oc.commitChanges();

Hi Andrew,

You don't show the relevant stack, so I can only guess. But I find the 
following code suspect:

    project.setObjectContext(oc);
    project.getCompany().setObjectContext(oc);
Setting ObjectContext explicitly on Persistent objects is never a good 
idea. Object should stay in the ObjectContext it was created in or fetched 
from). Any specific reason why you are doing that?

I am stuck on exactly what this message means and how to correct the 
situation.

Here are my table relationships.

Project               ProjectContact         Contact
---------               --------------------         ----------
ProjectID <--->     ProjectID
                              ContactID    <--->  ContactID

Here is my code.

                ObjectContext oc = UI.getObjectContext();
                for (Contact item : list) {
                    ProjectContact newItem = 
oc.newObject(ProjectContact.class);
                    project.setObjectContext(oc);
                    project.getCompany().setObjectContext(oc);
                    newItem.setCompany(project.getCompany());
                    item.setObjectContext(oc);
exception->newItem.setContact(item);
                    newItem.setProject(project);
newItem.setPrimeContact(ProjectContact.Type.NON_PRIME.getCode());
                    addItemCount++;

Here's the exception that is thrown when the newItem.setContact(item) is 
executed.
