Date params form issue

I'm getting some troubles with the tag and then updating my Date attribute from a model with the params sent.

Here is my tag:

    <g:datePicker name="data" value="${controle.data}" precision="month" 
        years="${(Calendar.getInstance().get(Calendar.YEAR)-70)..Calendar.getInstance().get(Calendar.YEAR)}"/>

When I println the "params.data" it says "struct", but I can't simply do:

model.data = params.data

the params comes with params.data_month and params.data_year with the respectives values in String like:

[[data:struct], [data_month:1], [data_year:2009]]

I tried to do then:

model.data = new SimpleDateFormat("MM/yyyy").parse("${params.data_month}/${params.data_year}")

but it rejects the value, alerting: "Cannot convert value of type [java.lang.String] to required type [java.util.Date] for property 'data'"

println model.data
println new SimpleDateFormat("MM/yyyy").parse("${params.data_month}/${params.data_year}")

--shows

Why not? Are you getting an exception, or are you just being mislead by outdated documentation? -
This is a feature since Grails 1.2. Conversion to a Date type will be performed, automatically.

As for the SimpleDateFormat issue, just add a day, like so:

model.data = new SimpleDateFormat("d/MM/yyyy").parse(
    "1/${params.data_month}/${params.data_year}")
