OK, I can pass f.i. a String from a Java class to flowscript..
But I can not pass a String[] (thun an array)..
My class is as follows:
public class EmpActivities {
public EmpActivities() {
}
public String[] activities() {
String[] result = new String[2];
result[0]="CCCCC";
result[1]="BBBBB";
return result;
}
}
And my flowscript:
var mc = new EmpActivities();
var acModel = activitiesForm.getModel();
acModel.addAnExistingActivity = mc.activities();
This works (so, I really don't know what's wrong on retrieving an array):
acModel.addAnExistingActivity = ["AAAAA", "BBBBB"];
Thank you for your help!!!
