I got it working now...I saw some helpful additional comments on the sourceforge page. I used the annotations now and did without a page file. I also added a library line to the application file. Another error was that I forgot the PageBeginRender interface so that the object was null when the page loaded as the method to create an empty object was not called.
But another question....I am trying to edit a an object that depends on another object/table which i would like to solve as a PropertySelection...preferrably without doing a PropertySelectionModel class for it. E.g.: Table with Cats ~~~~~~~~~~~~~~~ (mapped to Cat.java) id name owner_id 1 Felix 2 2 Garfield 1 Table with Owners ~~~~~~~~~~~~~~~~~~ (mapped to Owner.java) id name 1 Sally 2 Peter So if I want to edit or create a new Cat I want the Owner to be selectable as PropertySelection. <span jwcid="@bf:BeanForm" bean="ognl:cat" save="listener:save" delete="listener:delete"/> Just displays a text field for the owner_id.... has anyone got a good example how to do it? Or does it end up gettings a bit messy with lots of coding for a PropertySelectionModel class?
