Peter, I think I have found why layout look like this. We have following structure:
<js:Panel title="Component Explorer" width="25%" height="100%" className="Explorer"> <js:Tree id="contentTree" width="100%" height="100%" labelField="title" className="ExplorerTree" change="treeChange()"/> </js:Panel> Generated HTML: <http://apache-flex-development.2333347.n4.nabble.com/file/n60776/content_tree.png> If I change contentTree CSS to position:relative I will see "span" with "Everytghing" text and Tree started to work. I'm trying to understand why...
