I'm not sure what cause this. I checked everything but it didn't work so I had to load default set which solved the problem. (I assure you that I wasn't edit mode) I still wonder what was the problem..
No I think there is something seriously wrong with the outliner window. Prior to 2.8 selecting something in the outliner positively selected it in the 3d viewport. The outliner in 2.8 is erratic. Selecting something in the outliner does not necessarily select it in the 3d.
