Hi,
I'm trying to write a simple application using Seam Framework, based on the seam reference documentation. I have a search screen, that displays a list of entities. For each entity on the list, there's a hyperlink that can be clicked to display an edit page.
Seam reference tells the developer to write the hyperlink as <s:link> with <f:param>, and declares that param at pages.xml, so it can be passed to EntityHome.
So I'm facing a problem: the param is passed to EntityHome as String, and EntityHome invokes
E result = getEntityManager().find( getEntityClass(), getId() );
but my entity identifier is Long typed, so hibernate throws
org.hibernate.TypeMismatchException: Provided id of the wrong type. Expected: class java.lang.Long, got class java.lang.String.
How can I solve this?
Thanx,
Fábio.
