Hi,
In Properties View of runtime (or even the Properties View of .odesign file), when I click to a combobox to open items list, I found that the last item is blank (you can see in the attached image)

So how can I remove this unnecessary blank item?

Thanks.

Hi,

This is not a Sirius related question but a EMF one. The fact to have a
blank item comes from
org.eclipse.emf.edit.provider.ItemPropertyDescriptor.getComboBoxObjects().
To avoid that for your property, you could update your XXXItemProvider
to create a custom IItemPropertyDescriptor which override
ItemPropertyDescriptor.getChoiceOfValues() to remove the "null" value
from the collection. You can also ask your question on the EMF group
perhaps someone has a better solution.

Best Regards.
