Hi Philippe,

You're right. Can you please open one bug for each issue? I'll fix all
of them this month.
I have also a question concerning FraSCAti: do you plan to support
SCA-OASIS in the short term? before June?

Concerning the possibility to know the file and the line where there are
errors, Vincent will contribute some code for this in the following weeks.
However, I'm not sure that it'll be directly useable by FraSCAti. The
code is based on the XML editor.
I let Vincent say more about it.

A+

Hi Philippe, Stéphane,

The line resolution for errors indeed relies on the Eclipse XML editor.
I have succefully put this mecanism in place for other tools I'm working
on. And I plan to put it in SCA Tools very soon. But I don't think this
implementation works outside Eclipse. Or, at least, you won't be able to
compile it with Maven. Besides, line resolution won't be part of the SCA
builder (validator) but a part of the XML editor.

If we want to add line resolution directly in EMF, there might be a
solution, but I have just seen the hint and no code. It consists in
replacing the XmlHandler in the EMF parser and in storing line numbers
for every element. Since FraSCAti only uses EMF for reading, it would
not be too painful to use (in writing mode, we would also have to update
the line number on every save action).

However, how to do that concretely, I don't know.
You can check org.eclipse.emf.ecore.xmi.impl.XMLHandler for more details.

Also, check these answers from Ed Merks.

The WTP DOM implementation is indeed excellent in getting the line
numbers (even for attributes).

One last thing I forgot.
You can easily get the file location from an EObject.

Just work the URI retrieved with EObject.eResource().getURI();
The URI scheme depends on where EMF is used (can be file://,
platform://, etc...).
