Description

I am trying to have a Form inside a VelocityPanel, but I get the following Exception:

WicketMessage: Unable to find the markup for the component. That may be due to transparent containers or components implementing IComponentResolver: [MarkupContainer [Component id = form, page = simplevelocity.SimpleVelocityPage, path = 3:velocity:form.MyForm, isVisible = true, isVersioned = true]]

Root cause:

org.apache.wicket.WicketRuntimeException: Unable to find the markup for the component. That may be due to transparent containers or components implementing IComponentResolver: [MarkupContainer [Component id = form, page = simplevelocity.SimpleVelocityPage, path = 3:velocity:form.MyForm, isVisible = true, isVersioned = true]]

I also have a Label inside the VelocityPanel, which works fine.
