Problem with Save As functionality [message #216534]

Hi everybody!

I have a problem when I try to use the Save As functionality to save my
model and I hope somebody can help me. When I have my model done in the
diagram view, if I make some changes (for example add an attribute) and
try to save the model in a new file with the Save As menu the model is
stored in a new file but it is restored to the last point when I saved it
(in this case my new attribute would not be in the new file).

I dont know why this happens is that the expected behaviour or is it a
bug? Do you know how can I get my new changes saved in a new file without
saving before the actual file?

Thank you very much in advance!

Am I the only one experiencing this problem? Or is it the expected
behaviour? I tried with a very basic model and it happens too.

Its strange that nobody saw it because I think its a very important
functionality (to be able to save your changes in a new file).

Can anybody help me?

Hello John S.,

Well, this is how saveAs is implemented currently.. You can submitt a request
to modify this bevaviour and attach proposed patch to it. Generated ???DocumentProvider.doSaveDocument()
will be called to perform actual saveAs action.

Thanks Alex for your response. So thats how it is supposed to work

I know that I have to make some changes in the generated
XXX.DocumentProvider.doSaveDocument() but I dont know which changes. If I
try to do a saveAs, the info variable is set to null and I cant
obtain the resources from the actual model. If I just try to do a simple
save, that info has a value, so its resources are saved.

Can you give me an example or at least some tips/hints about what should I
do?

Thank you very much!

Well, actually thats not true. I mean I have the model information stored
in the diagramDocument variable
IDiagramDocument diagramDocument = (IDiagramDocument) document;

But when the newResource is made it seems that it doesnt have all the
information, so when its saved the actual differences between the new
model and the last saved model are not stored.

How can I store those differences in the new file? As you can see I dont
understand this very well... Any help is appreciated! Thank you!

Well, same with me. This functionality is implemented this way just because
I do not know a proper answer to this question… :-)

just an idea: try substituting URI of the current diagram resource with the
URI on “new” diagram resource (using Resiource.setURI()) and then save/reload
it.
