Hi all,
I am trying to make a simple EMF-GEF model editor. When I open a file with
the new editor it gives me the following error:
"Unable to create this part due to an internal error. Reason for the
failure: null argument:The editor input must be non-null"
I have taken a look at the parts factory class's method, it returns a
non-null editor part for my root part.
TIA,
Irfan Hamid.
PS: Clicking on the "Details" button gives me the following
org.eclipse.core.runtime.AssertionFailedException: null argument:The editor
input must be non-null
