So i'm trying to replicate the save and new button on the sales order line form, however i am trying to get it to pass the values of the previous entry to the new form, below is my current non working method:

this._save()
var form = this.form_view
var model = form.model
var handle = form.handle

var record = model.get(handle, {raw:true})
var data = record.data
var getcontext = record.getContext()

for (var attname in data) {getcontext[attname] = data[attname]}

return model.load({
    context: getcontext,     
    fields: record.fields,
    fieldsInfo: record.fieldsInfo,
    modelName: form.modelName,     
    parentID: self.parentID, 
    res_ids: record.res_ids,
    type: 'record',
    viewType: 'form',
}) .then(function (handle) {
    form.handle = handle;
    form._updateEnv();
    return form._setMode('edit');
})

So i thought that passing the values through within the context should then display the fields but this is not the case.

Is there anyway i can get it to display the fields?
