[xcore] References lower bound value not serialized [message #897602]

Hi,

I use the properties sheet page with the XCore editor to change the lower bound value of a Reference (not array) from 0 to 1. The properties sheet page works as expected but I realize that change is not reflected in .xcore file. So if I reload the model, the lower bound value is set back to 0.

Is this an error. I used that capability with .ecore to set basic constraints.

Thanks Wink

Hmmm. Those Ecore properties should be read only. You're expected
to edit the Xcore directly. Only the GenModel properties should be
changeable and they are converted to @GenModel annotations. Please
open a bugzilla to make them read only.

You should use bounds within [], e.g.,

Things like [0..*], [1], or [1..*] all work. Just a bare [] is the
same as [0..*] 
 
There should be no need to edit Ecore properties for any purpose...

Thanks Ed for the quick response.

I was not aware [1] was ok. Thanks for the tip. I'll open a bug.

Just a little comment.

Would it be great to be able to edit ecore properties via the properties sheet page. We should be able to change containment attribute in the properties sheet page and then the keyword contains reflected in the xcore. I do not understand the rationale why it is only applicable to GenModel. Should I raise a more generic bug (nice to have).

Thanks

No, I don't want to support that. Every type of change needs to be
mapped back to detailed source edits. That's a lot of work with a
hundred special cases.

There's a keyword for that; one that supports auto completion.

Does Java's editor support any editing via properties? Why not? For
GenModel there is no specialized syntax, only annotations, and the
mapping simple, i.e., the mapping to annotation properties can be done
reflectively.

If you want to edit Ecore, you can already do that. And you can export
to Xcore after you're done. It's sufficient.
