Hi Juliane,
templates and classes for pages or components have to be in the same package.
Secondly, pages (i.e. Start) must go to the pages subpackage whilst components
(i.e. Layout) must go to the components subpackage. The resulting package
structure for your example would be:
de.<yourdomain>.<yourappname>.pages.Start.java
de.<yourdomain>.<yourappname>.pages.Start.tml
de.<yourdomain>.<yourappname>.components.Layout.java
de.<yourdomain>.<yourappname>.components.Layout.tml
And another thing I am facing when creating new classes is that class reloading
notices when I have changed an existing class but does not notice for some
reason when I have added a new class. So maybe a restart of your context or
even your servlet container after having added a new class might solve the
problem.
Kind regards, nillehammer
