Multi Dataadapter (dev/prod)

I would like to use different Dataadapter depending on the context by passing a parameter to it.
 
I tried this solution but it doesn't work :
 
<propertyExpression name="net.sf.jasperreports.data.adapter"><![CDATA[$P{DataAdapterLocation}]]></propertyExpression>
<parameter name="DataAdapterLocation" class="java.lang.String" evaluationTime="Early">
    <defaultValueExpression><![CDATA["default/path/to/DataAdapterFile"]]></defaultValueExpression>
</parameter>
