[Validation] Markers missing Location [message #419041]

We have a project we recently converted to using EMF. As part of that, I'm
converting our old validation code to use the EMF validation framework. On
the test validation I've created (using a single constraint), I can
validate with the Diagnostician to get a Diagnostic, and then convert that
Diagnostic to an IMarker with the MarkerHelper/EditUIMarkerHelper class.
These markers show up in the Problems view correctly. However, they are
missing line numbers, which is the benefit we were hoping to get from
using EMF validation. Is there a way to get line numbers for these
markers, or does EMF not provide that functionality?

Kane,

EMF markers keep track of the actual object (using a URI) to which the
marker refers. But the location of each object in it's XML
serialization is not tracked.

In theory we could track such things as we're parsing, but of course the
first time you change something, the locations would change... We could
also do such tracking as we serialize. We've just never had time to
work on a synchronized source view.

Hi Ed,

I understand having other things to do :) Don't we all...

It seems to me that losing the accuracy of the line number/column is a
minimal issue, as I (and many other users, I imagine) would be
re-validating a model on changes. With an incremental builder, this isn't
resource/time intensive, and would maintain accuracy.

Of course, even if that weren't the case, if the user is going to edit the
code and the validation is off enough to be noticeable, the user can
always validate again.

I'll post these comments to the bug you gave as well. Good to know I'm not
the first to run into this.
