Hello,
I´ve got a question regarding the core properties associated with
Diagram nodes. I´ve got a ecore model with 5 Elements. 4 of these got a
number of specializations meaning that there are multiple creation tools
and node references that point to these ecore classes. I want to provide
the possibility that the user can insert "generic" nodes, where he can
specify the property values of the the underlying ecore class, which is
the behavior you get initially. For other nodes I initialize certain
properties with a value and would like those to be "fixed" meaning the
user can view, but not change them. As a third option I´d like to hide
some properties in the properties view for special nodes. The only
options I found to specify the visibility and edit behavior of the
properties reside in the EMF models and would apply to all diagram nodes
that reference the ecore class which contains the nodes. Can the
behavior I described above be achieved by adding things to the mapping
model (that I did possibly not find yet) or do I have to modify the
generated code? A custom property sheet is not required from my point of
view as I´d prefer to keep the generated view and alter it for those
special nodes. It´d be very nice if someone could instruct me on this.
I´ve searched the newsgroup but didn´t find a usecase that seemed
related to mine.
Greetings,
Christian

Does no one have a suggestion how I can achieve this? I´m sorry for
flooding the group at the moment, but these are really important issues
for my project. I hope I didn´t miss a existing solution for this
usecase. Thanks again for your support.
