show in project group summary per project also the status counters (as they are shown on the project groups pages)

I mean the total number of success builds/failure/error
I guess on the project groups page, it is the #subprojects

patch attached.

I don't think your patch is correct. You add nb success/failure/error on each project row, number are calculated from the build results of the project.
Maybe I don't understand the interest to have nb success/failure:error by project but I think it would be better to have the same nb success/failure/error on the group like it is shown in the groups list page

Ok I see your point.
I think a global statistics on a project life is nice.
My proposal : look at the attached screenshot.

It seems the page is more slow with your statistics (~7seconds to load a group that contain the whole Continuum project)

Yes this needs a more dedicated jdo query.
We can move this too a later release (or never ).
I will submit an other patch with only the "Project Group Last Build Result Overview" information.

do you think you can do the dedicated query before your holidays?

Simple implementation without nb success/failure/error per project.

simple patch applied.

We need a discussion on the dev list about the big patch. Olivier can you start it?

I close this issue for now as we have a simple state counter for the group (not by project). We'll can reopen a new issue if we want the solution proposed by Olivier but actually, I don't see the interest to have a counter by project based on build results state.
