Hello

I want to change the appearance of a graphical element based on a
boolean attribute of the DomainModel (selected{true,false})
Changing the Backgroundcolor would be enough.

http://wiki.eclipse.org/index.php/GMF_Archived_Newsgroup_Q&a mp;A#How_can_I_change_the_appearance_of_an_element_based_on_ its_domain_element.27s_attributes.3F

I red this wiki-entry and wondered how such a Constraint to select
between mappings would look like...
If that doesn't work maybe someone could give me a hint to find some
other solution.

thanks
Thomas

It should be: "self.selected" and "not self.selected" :-) But. currently
your diagram will not be updated on changing this attribute in the domain
model. So, I suggest you to stick to the second solution proposed in this
wiki page.
