Hi!Using saveChanges() and defaultEditingContext() in the same code line is a really bad idea. The defaultEditingContext should only be used to store long-living read-only objects.
To make changes, you should use local ECs. If you are modifying and writing objects with the default EC, you'll quickly loose control on what is on the default EC, and nothing will work at all. An EC is like a sandbox, a very intelligent and powerful transaction (I'll be beaten for using the T word, I know). So you should keep its changes as local as possible. "It's a local EC for local EOs".

Hello, We have an intermittent behaviour as follows:We have an object (build via EOModeler) fetched into the session's default editing context; which we are able to update successfully via WO component bindings / java code via session ().defaultEditingContext().saveChanges(). We then do a session ().defaultEditingContext().refreshAllObjects(), but a subsequent change to the object (via a "setter" in java code) is only sometimes updated by a subsequent session().defaultEditingContext ().saveChanges(). This behaviour appears totally random - on debugging we notice that sometimes the EditingContext's "updatedObjects()" reflects the update done by the setter, and sometimes it does not.Is this a known problem?Are we making assumptions that we shouldn't be i.e. is it correct to assume that if we do...1. fetch object into session's default editing context. 2. do updates on object via components / java code. 3. save object via: session().defaultEditingContext().saveChanges(); session().defaultEditingContext().refreshAllObjects(); 4. do further updates on object via java code. 5. save object again via: session().defaultEditingContext().saveChanges(); session().defaultEditingContext().refreshAllObjects(); That step 5 should save the changes? Appreciate any assistance you can give.
