Right now, the Layouts are not saving any Pen Information and you need to fix the Pen you have selected at the moment manually to get the right publishing results for all alements drwan directly in the LAyout. The Elements vontained in Drawings use the Pen-Set saved with the View.
It's necessary to have the possibility to save the Pen directly with the Layout to avoid problems with the representation.
