I haven't used MDL before, but moving code around I found that you are not nesting the MDL tags properly. The #mdlLayout must contain all the other elements, including the header. So using your own classes the best way would be to do the following: TBApplicationRootComponent>>renderContentOn: html html mdlLayout beFixedHeader; with: main TBSScreenComponent>>renderContentOn: html html render: header html mdlLayoutContainer: [ self renderPageContentOn: html ]. TBSScreenComponent>>renderPageContentOn: html self subclassResponsibility TBPostsListComponent>>renderPageContentOn: html html heading level:2 ; with: 'Here comes the sun' Regards. Esteban A.

Hello,

I try to make my first seaside project. But I ran into a problem that I do not see how to solve,

The image can be found here : *https://www.dropbox.com/s/8dt7xj1y6na5jog/Paintings.image?dl=0 *and the changes file here : *https://www.dropbox.com/s/dnsslrnpxgy0ha8/Paintings.changes?dl=0

*The problem is that I do not see the text "Blog post here" under my header.

I use Pharo version 7 on Windows 10, Seaside latest and MDL latest.

I hope someone can help me figure out why this happen and how to solve this

Regards,

Roelof Wobben
