Hi,
When I have selected two or more elements in my model the propsheet is
empty. I want it to show the attributes of these two(or more) elements.
Thanks in advance!

Stanislav,

By default this ItemPropertyDescriptor method always returns false:

public boolean isCompatibleWith(Object object, Object anotherObject,
IItemPropertyDescriptor anotherItemPropertyDescriptor)

In this bugzilla we're looking at supporting another GenFeature property
to mark properties that should support multi-selection.
<https://bugs.eclipse.org/bugs/show_bug.cgi?id=217280>

https://bugs.eclipse.org/bugs/show_bug.cgi?id=217280

The problem is that each property value is set separately and there
appears to be no mechanism that would allow me to create a single
compound command that would allow undo to undo all the multiple changes
at once...

Ed,
Is there a way to show not only the matching attributes between the
selected elements but also the other?

Stanislav,

I'm not sure I understand. The whole multiple selection thing works
poorly in my opinion. I.e., if you select two things with different
values, what's displayed? Maybe that's what you're asking. I'm not sure
how it is even possible to control what's displayed given the the
property descriptor itself doesn't know ithat t's being used in a
multiple selection context (as far as I've been able to figure out).

Not really! I am not confused of what will be shown for the same attribute
(with different values) of two selected elements.I've seen that it is not
working very well. I need to show in properties view the attributes of
these elements which are different(element A has attribute int x; element
B has attribute string y; when I select these two elements there is
nothing displayed in the properties view but I need to display(and edit of
course)x and y attributes.

Stanislav,

That's not the way the properties view works though. It only shows the
attributes that are in common (that are compatible). I'm not sure
there's anything you can do about that short of taking over the whole
properties view and reimplementing most of the logic...
