I had a look, but was able to use a List without problem (6.1.CR2):
1) Made a Maven-ized JAR containing the following class:
package org.anstis;
import java.util.List;
public class MyListClass {
private List myList;
public List getMyList() {
return myList;
}
public void setMyList( List myList ) {
this.myList = myList;
}
}
2) Uploaded JAR to the workbench's Artifact Repository
3) Added a project dependency on this artifact
4) Added an Import Suggestion for java.util.List
5) Created a new Guided Rule
6) Imported MyListClass and java.util.List (Config tab)
7) Created the following rule:
package org.mortgages;
import java.lang.Number;
import java.util.List;
import org.anstis.MyListClass;
rule "r1"
dialect "mvel"
when
MyListClass( myList.size() < 5 )
then
end
You need to use an "Expression" to use the "size()" method call (as it is
not a field, but a method call). Fields are "getXXX" or "setYYY" or public
members.
With kind regards,
Mike
