I have a test application (based on example/TreeVirtual_3.html) that works fine if the tree is instantiated using
tree = new qx.ui.treevirtual.TreeVirtual(headings); It fails, though, if I subclass TreeVirtual like this: qx.Clazz.define("myclass.widget.tree.Tree", { extend : qx.ui.treevirtual.TreeVirtual, construct : function(headings) { this.base(arguments, headings); } }); and then instantiate the tree using tree = new myclass.widget.tree.Tree(headings); The error produced is: 002970 ERROR: myclass.widget.tree.Tree[434]: Modification of property "tableModel" failed with exception: Error - Objects of class 'myclass.widget.tree.Tree' do not support the event 'appear' It's failing in Target.js:89 due to the event being "unsupported". Am I doing something wrong, or is this a bug in Clazz.js? Thanks, Derrell ------------------------------------------------------------------------- Take Surveys. Earn Cash.
