Identifying diagram elements? [message #646900]

Hello,

I'm wondering whether there is a smarter way to do this... When updating or
layouting my (sometimes very complex) diagram elements, I have to somehow
iterate through the existing elements and identify them - which of the 15
Shapes or Texts is the one I want to update? The link to a business object is
not enough, because most of the time I've got multiple diagram elements for a
single business object. Right now, I've resorted to using the
PropertyContainer methods - I'm simply 'tagging' every diagram element with a
string to identify it by later on. This looks a bit clumsy to me - is there a
better way?

Thanks
Volker

Volker,

I assume you are using:

            Graphiti.getPeService().setPropertyValue(mainShape, "id" , "TopContainer");

I am using this for some time now. Works well, and I have not found a better way yet.

Yes, exactly.

It works, yes, but it feels so - GMF-y ;-)

Volker,

I also can't think of a better way. For identification Graphiti offers the
linking and properties mechanisms, depending on your scenario you might also
use the type of the diagram object for identification (if the types
differ...), but that's it...

Properties are the most generic thing you probably can think of (that's
maybe also the reason why they feel so GMF-y... ;-) ), so they hopefully
help to solve all kinds of identifications issues; the downside is of course
their handling. If you have any idea how to better solve this let me know,
it could end up as an enhancement.
