Dan Haywood resolved ISIS-1269.
-------------------------------
Resolution: Fixed
> Deleting an object from a list can cause NPE when that list is re-rendered.
> ---------------------------------------------------------------------------
>
> Key: ISIS-1269
> URL: https://issues.apache.org/jira/browse/ISIS-1269
> Project: Isis
> Issue Type: Improvement
> Components: Core
> Affects Versions: 1.10.0
> Reporter: Dan Haywood
> Assignee: Dan Haywood
> Priority: Minor
> Fix For: 1.11.0
>
>
> For example, in the todoapp the home page displays all the todo items, not
> yet completed vs completed.
> If select "Buy Milk" (when not complete) and delete it, then the NPE is
> thrown.
> This is ultimately because the list returned from ToDoItem#delete() is stale:
> {code}
> public List<ToDoItem> delete() {
> // obtain title first, because cannot reference object after deleted
> final String title = container.titleOf(this);
> final List<ToDoItem> returnList = actionInvocationContext.isLast() ?
> toDoItems.notYetComplete() : null;
> container.removeIfNotAlready(this);
> container.informUser(
> TranslatableString.tr("Deleted {title}", "title", title),
> this.getClass(), "delete");
> return returnList;
> }
> {code}
> It ought not to return the current object about to be deleted.
> Even so, we can handle this application programming error easily enough, by
> filtering out any null objects.
