Hi Konstanin, I don´t think Filips post was irony. It really is simple. Anyway answering your question: Simply returning a component from a getter (in your case a Link from getMyDynaObject) won´t cause tapestry to render it. For a component to be rendered you have to place it somewhere in the template.
The eplanation of the strange behaviour you see is you handing over a Link to a Grid as a data object. The default behaviour of Grid is to "scan" the data object for simple properies (i.e. a public getter and corresponding setter are present and getter returns simple types like Integer, String, Date etc.) and display the values in a table. The only property a Link contains is anchor (look here: http://tapestry.apache.org/tapestry5/apidocs/org/apache/tapestry/Link.html). And that is displayed. To achieve what you want you have to use <t:parameter> within the Grid and place some type of Link-component in the template. Look here for example: http://tapestry.apache.org/tapestry5/tapestry-core/ref/org/apache/tapestry5/corelib/components/Grid.html The UserList.tml right at the middle of the page.
