OK, I tried that. Still no luck. I also went back to just using bind:
<lift:CategoryOps.editor form="POST">
<category:id />
<category:name />
<category:submit />
</lift:CategoryOps.editor>
And
object categoryVar extends RequestVar(new Category())
def category = categoryVar.is
def editor(xhtml : NodeSeq) : NodeSeq = {
def addOrUpdate() = {
if (category.name.length == 0) {
error("emptyCategory", "The category's name cannot be blank")
} else {
Model.merge(category)
redirectTo("/admin/categories/")
}
}
val currentId = category.id
bind("category", xhtml,
"id" -> SHtml.hidden({category.id = currentId}),
"name" -> SHtml.text(category.name, category.name = _),
"submit" -> SHtml.submit("Save", addOrUpdate))
}
Everything works just fine on add, but on update the form is not
populated because category is a new Category, not the one from the
database (I checked).
Any ideas?
Chas.
