The Google GWT TabLayoutPanel is working fine on Chrome and Firefox but currently on IE8 only the first tab is visible. I ran into this problem a few days ago. But as always with such kinds of problems in software development you’re probably not the first one. The issue shall be fixed in the next Google GWT release 2.0.1. Until then you can add
.gwt-TabLayoutPanelTab { float: left; }
to your CSS stylesheet.
