I am working on Tutorial 3.3, step 6&7 in GTK Web GIS 5th edition. I have followed the tutorial to a T and I cannot get the dynamic content panel to come up. I have a space after the colon, I have all the correct data connected, and I cannot figure out why it won't show up when I select it. I even started the tutorial over and did it from scratch, and nothing helps.
Did you ever figure this out? I'm trying it now and having the same issue.
