Andrey Razumovsky updated CAY-1080:
-----------------------------------
Attachment: patch-CAY-1080-2.txt
New patch, with changed behavior around #2 and #3
#2 Fixed that
#3 I think I know why you cannot paste an entity - previously you needed to
select DataMap to do that (so, when you press 'Cut', 'paste' button is still
disabled). As this seems quite unintuitive, I decided to enable pasting an
entity when another entity (or query, or procedure) is selected - it will be
pasted to parent datamap. Hope this helps.

> Support for copy/paste of entities/attributes/relationships.
> This is GSoC 2008 task.
> Some of my ideas follow.
> We can implement copy-paste in two ways.
> First: the buffer is valid only within a sole project. So when you open
> another project, copied data is lost.
> Second, the buffer is stored in whole modeler application, or even system
> buffer. This allows to copy data between different projects, but is more
> complex because we need to create shallow copies of entities, attrs etc.
> Personally I use only one cayenne.xml currently.
