Hi All,
I'm trying to do a simple example of loading enums programmatically
following the Drools Guvnor Docuemntation.
I'm on Drools Guvnor 5, Java 1.6 running under Jboss.
I'm trying to define this 'data enumeration/drop down list'
package opensource.test;
import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;
public class SampleDataSource2 {
public Map<String, List<String>> loadData() {
Map<String, List<String>> data =
new HashMap<String,List<String>>();
List<String> d = new ArrayList<String>();
d.add("A");
d.add("B");
d.add("C");
d.add("D");
d.add("E");
data.put("Employee.band", d);
return data;
}
}
The jar containing the SampleDataSource2 has been defined as a model
within Guvnor and I defined another declarative model Employee with fields
name,band,rating.
Here's what I put in the 'Data enumeration' text window
Employee.band =(new SampleDataSource2()).loadData()
When validating the Data enumeration from Guvnor, I get the following
error:
Unable to load enumeration data.
unable to resolve class: DataEnumSource
Error type: org.mvel.CompileException
Any help will be highly appreciated ...
Thanks,
Nilima
