Hi,
don't know whether this is a bug so I'll ask here first. In the wicket tree
examples, when I get a WicketRuntimeException in the
org.apache.wicket.examples.tree.BeginnersTreePage when I set a model to the
page as follows:
public BeginnersTreePage()
{
setDefaultModel(new CompoundPropertyModel<String>("bla")); // <-- this is
the new line
add(new DefaultNestedTree<Foo>("tree", new FooProvider()) {
...
The exception is
Root cause:
org.apache.wicket.WicketRuntimeException: Property could not be resolved for
class: class java.lang.String expression: tree
