<h:selectOneMenu> with <s:convertEntity/> and <s:selectItems
I'm trying to present a drop-down list for users to select from which is built from a list queried from the database. I will attach the selected entity to another entity.
The problem is that I get value="0" for every in the list and I get this exception (full dump at bottom) when submitting the form with a selected value:
javax.servlet.ServletException: Provided id of the wrong type. Expected: class java.lang.Long, got class java.lang.String
So I put a breakpoint in EntityConverter.getAsString and see that whereas the examples have the value parameter set to an object of an actual class (e.g. Continent in seam-ui), I have a Provider_$$_javassist_21 object. Looking into the object, the handler.target object is the data that I care about. Yet the getIdFromEntity() call returns null as found directly in the javassist subclass.
Given that all my code is very similar to the example code I don't know where to look from here.
thanks
