DB Table to populate a List of values

jirazazabal — Fri, 17 Jun 2016 15:53:54 -0400

Hi all,

I'm newbie about AI designer. I'm trying to do something that it should be easy. I want to load a list of values in a Dialog (selectOneMenu) from a DB table. Suppose I have some employees. I want to create a new employee, so I need to assign it to amn existing department. So, I need an object List<department> in the Dialog interface to use it in the selectOneMenu control and save department code when I save this employee data to database.

I'm not finding the way to connect the DB step when I make this query to the dialog step.

Can you help me? Any documentation about this kind of tasks?

List converted from an Enum array in Ivy Script doesn't work correctly

Genzer Hawker — Thu, 12 Mar 2015 08:27:40 -0400

Today I found something looks like a bug in Ivy Script.

In Ivy Script, I want to have a List of all the elements of an enum, say WorkflowPriority, I simply call WorkflowPriority.values(). However, the instance of List returned by the call doesn't work correctly, especially with operation contains and remove.

Here are the tests that I made to check:

(This is an Ivy Script snippet)

import org.junit.Assert;
import com.genzerhawherk.bugs.Lists;
import ch.ivyteam.ivy.workflow.WorkflowPriority;

// Below are all failed tests
Assert.assertTrue(WorkflowPriority.values().contains(WorkflowPriority.HIGH));

List<WorkflowPriority> withGenerics = WorkflowPriority.values();
Assert.assertTrue(withGenerics.contains(WorkflowPriority.HIGH));

List fromEnums = Lists.fromEnums(WorkflowPriority.class);
Assert.assertTrue(fromEnums.contains(WorkflowPriority.HIGH));

List fromEnumVarargs = Lists.enumVarArgs(WorkflowPriority.HIGH, WorkflowPriority.EXCEPTION);
Assert.assertTrue(fromEnumVarargs.contains(WorkflowPriority.HIGH));

// Below are all passed tests
List listComprehensive = [WorkflowPriority.HIGH];
Assert.assertTrue(listComprehensive.contains(WorkflowPriority.HIGH));

List newPriorities = new List().addAll(WorkflowPriority.values());
Assert.assertTrue(newPriorities.contains(WorkflowPriority.HIGH));

List fromList = Lists.toArray([WorkflowPriority.HIGH]);
Assert.assertTrue(fromList.contains(WorkflowPriority.HIGH));

List fromVarArgs = Lists.normalVarArgs(WorkflowPriority.HIGH);
Assert.assertTrue(fromVarArgs.contains(WorkflowPriority.HIGH));

List<WorkflowPriority> manuallyConstructed = new List<WorkflowPriority>();
manuallyConstructed.add(WorkflowPriority.HIGH);
Assert.assertTrue(manuallyConstructed.contains(WorkflowPriority.HIGH));

The bug particularly relates to converting <T extends Enum<T>> T[] into a List<T>

Below is the class Lists I use in the test

public class Lists {

    public static Object[] toArray(Collection<?> collection) {
        return collection.toArray();
    }

    @SafeVarargs
    public static <T> T[] normalVarArgs(T...elements) {
        return Arrays.copyOf(elements, elements.length);
    }

    public static <T extends Enum<T>> T[] fromEnums(Class<T> enums) {
        return enums.getEnumConstants();
    }

    @SafeVarargs
    public static <T extends Enum<T>> T[] enumVarArgs(T...enums) {
        return enums;
    }
}

How to get the users tasklist

HaraldWeber — Thu, 18 Sep 2014 14:12:03 -0400

How can i get the task list of the current logged in user without the permission TaskReadAll.

All methods i tried call getTaskQueryExecutor which needs the permission TaskReadAll.

I think the User should be allowed to read it's own tasks.

Getting a list as a result from an ivy webservice

Björn — Wed, 09 Apr 2014 11:40:46 -0400

I created a webservice in ivy, which requests a string as input parameter and returns as result a string and a list (of a custom data class Betreibung).

I can call this webservice from another ivy project and save the result in corresponding attributes. But as I can only save the list result "as List" and not "as List<betreibung>", every resulting List element is not of the class "Betreibung" but of the class "namespace.unknown.Betreibung". For this reason I cannot use the saved list entries later on.

I created a short video to clarify my problem (in german only):

Best Practice for filling a List in a loop

Björn — Fri, 22 Nov 2013 10:52:25 -0500

I'm using Xpert.ivy Designer 5.1.0 (Lauberhorn) S6. I tried to fill a List in a loop:

In a form I ask the user, how many entries the list will have (numberOfIterations)
With an Alternative Switch element I'm ensuring, that the following steps are executed as often as the defined number of iterations:
In a form I ask the user for the attributes of the list entry (attribute one, attribute two)
In three different variants I add the new list entry to the list. Only the most time consuming variant works. The other variants don't work as expected. I suppose, this is a bug.

To better understand, please watch the screencast on YouTube (2 minutes).

An answer until 25.11. evening would be very appreciated.
