[news.eclipse.dtp] Re: [ODA Ecore] Connection Profiles and Connection Pr

[Tim Myer <timezra@xxxxxxxxx>]

Hi John,
A quick update on this: I believe the bits are ready to get this feature 
working as you have requested.  Unfortunately, the change will break 
existing reports because of the way we currently store our properties 
and the way we put the file URI in those properties.  I will need to get 
Jeff's second pair of eyes on my code to make sure everything looks good 
before checking in and to make sure he is comfortable committing 
breaking changes.
These are the latest changes.  Please let me know if they sound like 
what you need:
1.  It is possible to create a Connection Profile for the Ecore ODA data 
source.  The Connection Profile stores the URI for the ecore file.
2.  It is now possible to use BIRT property binding to dynamically set 
the URI of the ecore model (the data source property is exposed publicly).
3.  There is now a 3rd option on the data source selection dialog page 
that allows a user to configure a literal URI for the ecore model (as 
well as options for using a filesystem or workspace resource, which are 
browsable as Ed Merks noted in another thread).

Note that I have not exposed the DataSet properties (the queryString or 
the column list) for dynamic property binding.  This would represent 
another breaking change if the feature were requested in the future.

One thing -- I would probably ask for your help in verifying that the 
implementation does what you expect, as I am not sure how I would set up 
a functional test case for the Connection Profile or Connection 
Properties features.
Let me know if it sounds like these features suit your needs.
Thanks for your patience.
