After deleting a list item node, saving will cause an error (Save Failed
java.lang.NullPointerException) and a warning
The warning contains more information, posted below
basicly the save failes and has no result but it returns OK so it expects a result and errors out.
To avoid the problem i made a custom delete action. However when i delete this item it cannot be saved either because of an missing EObjetdescription or feature. (second stacktrace below) This safety check is a bit too strong for me. Because the situation in the textual source can happen. For example you use a variable but its never declared, you can save the representation/file but with an warning that its never declared. Anyone got a solution to atleast save wihout checking if the EObject/description is used somewhere.
java.lang.NullPointerException

Hi,
Which version of Sirius are you using?
There are some changes recently [1], [2] about the saving of the session.
I have no idea about the second part of your post concerning xtext.

Hello,
The exception is about saving diagram with invalid model. As i see your given log:
java.lang.RuntimeException: A value for feature 'variable' is missing but required.
Semantic Object:...->...->I...->...->VariableExpression
I also face the same case.
The coming question is How to customize the NullpointerException message box when doing save with invalid model.
For example, when saving with invalid model => a friendly message look like "...unable to save the diagram due to...blabla.."
Thanks,
Thanh Huy LE

As mentionned by Cédric Brus in his "Sirius + Xtext = <3" EclipseCon
presentation [1][2], one solution consists in add model operation in
your tool (creation, direct edit, delete tool, ...) to always produce a
valid or serializable model. You might also try to reduce the
sensibility of your XText grammar and make it less strict for the
serialization.

When you delete an element, Sirius is intended to look for inverse cross
references and delete those references to the deleted objects. But in
your case this could produce some non serializable elements.
An idea could be to react to changes affecting you model (tools,
property view, ...) at the end of each transaction: you could add a
ModelChangeTrigger with priority=0 and a NotificationFilter targetting
the semantic resources to the SessionEventBroker, equivalent to an
aggregate precommit resourceset listener but it will allow you to make
the change before the first refresh (computation of the Sirius internal
model from your semantic model and you VSM) of the opened editors. You
might also have to look into DanglingRefRemovalTrigger to see how to
disable the RefreshEditorListener for the current precommit loop
iteration when you make modification in your semantic model to avoid to
trigger the refresh several time.
In your ModelChangeTrigger, you could detect the
