When you go to edit, are you passing the Category to be edited into the
categoryVar RequestVar? For instance, in your listing code say you had
something like:
def list (xhtml : NodeSeq) : NodeSeq = {
Model.createQuery[Category]("from Category").findAll.flatMap({category =>
<tr>
<td>{category.name}</td>
<td>{Shtml.link("/admin/categories/add", () => categoryVar(category),
Text("Edit"))}</td>
</tr>
}
Otherwise I don't see in your code where the categoryVar is being populated
other than the default (new Category()).
