Custom Behaviour with GMF [message #487802]

Hello,

could anybody of you give an easy example of how to use the
CustomBehaviour? I already tried to comprehend this guidance, but it
didn't work for me:
http://www.eclipsecon.org/2007/index.php?page=sub/&id=37 39
I only arrived at the 8th slide and there I fail by creating the
ModifyAttrCommand class, because eclipse advises me to add a constructor
with these three parameters: domain (TransactionalEditingDomain), label
(String) and affectedFiles (List)
But the Constructor shown in the presentation only needs one parameter
attr (EAttribute). So with which values the three parameters must be
initialized (especially the domain)?

thanks,
Bastian

Bastian,

there are static helper methods in TransactionUtil called
getEditingDomain for EObjects, Resources etc.
As far as I know you can use that domain. I'm not aware of that file
list. I usually leave it null.
