Hi all,
I get a ConcurrentModificationException when saving a resource after
getting and modifing its content, and I don't understand why...
I reproduced the error by modifying the CDO example project:
In project cdo.examples.ui -->
cdo.examples.ui.internal.actions.LoadResourceAction, I modify as follow:
....
private void loadResource() throws Exception {
.... // create resource manager
.... // load content of resource1
// Populate the model from the second resource.
System.out.println("--> TEST: Populate the model from the second resource");
Library library2 = (Library)resource2.getContents().get(0);
Book book = (Book)library2.getBooks().get(0);
book.setTitle("hello"); // my modif: try to update the book title
....
resourceManager.commit(); // commit modification
resourceManager.stop();
----
Once the library resources have been created, I invoke the Load library
resources to run my updates and the error happens when commit is invoked.
I get the same error if I update the book title after recreating a new
resource manager with a new resource set (just after the
resourceManager.stop()).
First, I would like to understand why ;), and also what are the
differences between this way of modifying the model and the way showed
in the example (that is via the cdo editor).
Thanks
Yannick

Yannick,
It's simply a bug. I've fixed it and tomorrows maintenance build will
have the correction.
If you want to read about the cause refer to
