I created JavaDelegate:
In process I call this delegate and after that I have a user task.
When I set complex variable there is an error on Active Tasks dashlets:
Help please
public class TestDelegate extends AbstractJavaDelegate {
/** {@inheritDoc} */
@Override
public void execute(DelegateExecution execution) throws Exception {
int length = 3;
List<Map<String, String>> list = new ArrayList<Map<String, String>>(length);
for (int i = 0; i < length; i++) {
Map<String, String> map = new HashMap<String, String>();
String iStr = String.valueOf(i);
map.put("id", iStr);
map.put("Name", "Name " + iStr);
map.put("Prop", "Property " + iStr);
list.add(map);
}
execution.setVariable("my_result", list); // NOT Working
//execution.setVariable("my_result", list.toString()); // Working
}
}
In process I call this delegate and after that I have a user task.
When I set complex variable there is an error on Active Tasks dashlets:
