When setting the the build trigger "build after other projects are built" on a
free-form (shell) project it seems OKAY when you press "save"., However, if you
go back to the "Configure" page the value (and setting) is not there. Seems like
this doesn't work. The project doesn't seem to be triggered by the other project
either (not only a visualization issue).

The error is found in hudson 1.149.
