Take a look at the XMLForm. It solves this kind of problems, such as mapping
your data to your form fields, mapping request parameters to your data
model, rules-based validation. See below for more:

If for some reason you don't want to use XMLForm then you can simply write a
transformer that performs this.

And you would also add another action too. I'd use one action to get the
data and then will use either request attributes or session to pass the data
to a transformer which would fill in your form. It really worth to take a
look at the XMLForm.
