can't propose a merge spanning projects or packages

This isn't an oversight, but is a flaw. This is by design as the app servers don't have direct access to the underlying branches (right now), and as an approximation we check that the branches have the same target (source package or project).

Sorry about this 'me too!' posting but the launchpad tour currently boasts "making it easy to share code [...] across projects" (see [1]), so I am seriously disappointed by this unexpected behaviour.

I have a project to maintain a stable branch of OpenERP as the OpenERP bug fixing policy prevents community bug fixes on the stable branch of the official project (soul sucking hybrid business model). However, we among others post branches of the OpenERP project that fix such bugs on the stable version, and I would like to manage merge requests of these branches with our own project.

Indeed, the two branches in their respective projects have a recent common anchestor and bzr has no problem doing the actual merges, but due to this bug, Launchpad keeps telling me that "This branch (under openobject-addons) is not mergeable into lp:therp-backports".

For example: https://code.launchpad.net/~therp-nl/openobject-addons/l10n_nl-fixes cannot be merged in lp:therp-backports

I would really like this flaw to be solved but of course, with only three people being affected in three years we do not stand a chance...

Cheers,
Stefan.

Hi,

It seems me too is affected by this bug! I am trying to merge my change proposal of my branch: lp:~synerpgy/synerpgy-projects/synerpgy-extra-trunk into the target branch: lp:openobject-addons/extra-trunk. I am not able to understand what is going wrong.

Thanks and Regards!
Vivek

Unless there is a reason for this which I don't understand, I too would like to see this behavior changed.
