Oops in the previous code it's actually :
class AddInvoice {
val clientBox = ViewClient.currentClient
val client = ViewClient.currentClient.open_!
def add (inhtml: NodeSeq) : NodeSeq = {
val inInvoice = Invoice.create
def processEntry () {
S.notice ("Test " + client.firstName)
inInvoice.client (client)
inInvoice.save
S.notice ("Entre : Description " + inInvoice.description + "
Montant : " + inInvoice.amount)
}
bind ("e", inhtml,
"description" -> inInvoice.description.toForm,
"amount" -> inInvoice.amount.toForm,
"submit" -> SHtml.submit ("Ajouter Facture", processEntry))
}
}
The client* are in the class not the method... works great with a
statful snippet tought
