Just a quick report on the fact that although changing the layout is working fine, the state of the Toolbox > Layout does not reflect the actual state of the space. It is then possible to have a layout with 'm' column applied to the space and the toolbox showing the' n' column layout as selected layout. By selection, I mean the rectangle around the layout. See attached 'layout' screenshot.
- set a 1 columns layout on space X
- logout and back in
- look at space X again and check what the Toolbox > Layout portlet indicates (look which of the four layout icons is selected)
EXP: selected icon shoud match actual space layout
ACT: three out of four chances that it does not. It seems to me as if the same layout icon is always selected, no matter what the space is set to be using.
