There should be implicits that allow you to bind to a Box of a NodeSeq, so you
can bind to prodBox.map(_.toForm). Otherwise bind to
prodBox.map(_.toForm).openOr(NodeSeq.Empty) etc.

Hi.
Boxes are giving me a hard
Well it depends on precisely what you want. If you want your snippet
to become empty if the product is not there, try:
productBox.map(product = {
bind(product, ns, ...)
}).openOr(NodeSeq.Empty)
If you want only certain bind positions empty, do the same thing
inside the bind:
That's my code:
val product = Product.find(id)
producto.map(product =
bind(product, xhtml,
url_enlace -- /product/ + product.id.toString ,
)
).openOr(NodeSeq.Empty)
}
and I get this error:
[INFO] use java command with args in file forced
Because the compiler interpret your expression as you expect. Instead
of:
url_enlace - (/product/ + product.id.toString)
which is what you wanted, it got:
(url_enlace - /product/) + product.id.toString)
which it can do because it can take an arbitrary object:
(url_enlace - /product/):
Operators starting with - and + have the same precendence so they are combined
left to right. Thus you are concatenating a BindParam with a String, returning
a String.

It worked when I put the () around the bind
Precedence is determined by the first character of an operator.

Yup

So, as - begins with - then it has the precedence of the operator

It worked when I put the () around the bind param
and the question is ... why?

So that doesn't seem to be a box-related thing so much as a bind
argument related thing, probably because you have a precedence
problem... try:
I adapted the code but not the error, Producto is Product in Spanish.
