field-to-result ¿default-value?

[david.cuenca]

I have a simple-method, implementing a service, where I get some values
from the Entity Engine in a map. Then I copy some fields from this map
to the service result field.
Well, with some conditions the map that I obtain from the Entity Engine
is empty (and has to be empty). So I would like to be able to use
something like
<field-to-result field-name="product.productName"
result-name="productName"  default-value="NA" />
But there is no solution as simple as this, because the clause
default-value is not avaliable. Which is the most elegant solution to do
this?

Thank you

Do a pre-check on product.productName using <if-empty>. If empty, insert your default value into
the env variable.

Alternatively,
<set field="productName" from-field="product.productName"
default-value="NA"/>
<field-to-result field="productName"/>
