Artifact download in branch-plans not working?

Hi Atlassians,

i´m not sure if this is a missing feature, or if i´m just to stupid to find the right configuration.

I have set up a plan with two stages. In the first stage the source code is checked out, build and tested. The result is a shared artifact with the results of the build. In the second stage, i download the artifact and copy it to a remote server via a script. For the master-branch this works fine.

Then i have configured branch-plans. But when i build a branch in the second stage of the branch-plan not the artifact created during the first stage is downloaded but the artifact created in the last run of the master-build-plan (=the last build of the master-branch). In the log i can see this happening:

19-Jul-2013 13:07:43 Build GeDok 5 - Gated Build - Refactoring_Tim - Deploy GeDok 5 #2 (DDEV-GB5-DEPLOY-2) started building on agent Default Agent

19-Jul-2013 13:07:44 Artifact [GeDok5_Gated_Files] downloaded successfully in 0s

GB5 refers to the branch-build (Gated build #5). The downloaded artifact is "DDEV-GB-65 artifact", which is the artifact created during the 65th run of the master-build-plan.

Whats going on here? How can i tell him to take the correct artifact?

Please help. Thanks.
