Hi,

back on a Scout project again I would like to use the PlannerField in conjunction with Scout 6.0. I never used the planner before and the best information I have found is a gist created about two years ago. Helpful and clearifying the general concept - but nevertheless I got stuck (or perhaps confused) in the actual implementation. Can anybody point me to the right direction with a short example or some code hints.

Thanks in advance

Stefan

After further investigation I still run into a problem. But in the meantime I am not sure if it is a problem of my understanding. More and more I believe it could also be a bug in 6.0.100.RC4.
With a planner field in a form like this

	@Order(1000)
	public class MainBox extends AbstractGroupBox {
		
		@Order(101000)
		public class TrainerPlannerField extends AbstractPlannerField<TrainerPlannerField.Planner, Long, Long> {
			
			public class Planner extends AbstractPlanner<Long, Long> {
				
				@Override
				protected Set<Integer> getConfiguredAvailableDisplayModes() {
					return CollectionUtility.hashSet(
					        IPlannerDisplayMode.MONTH,
					        IPlannerDisplayMode.YEAR);
				}

				@Override
				protected int getConfiguredDisplayMode() {
					return IPlannerDisplayMode.MONTH;
				}
			}
			
			@Override
			protected List<Resource<Long>> execLoadResources() {
				List<Resource<Long>> rl = new ArrayList<Resource<Long>>();
				Resource<Long> r = new Resource<Long>(1L, "Test Resource");
				Activity<Long, Long> a = new Activity<Long, Long>(1L, 4711L);
				a.setText("Test Activity");
				Calendar start = Calendar.getInstance();
				start.clear();
				start.set(2016, 9, 24, 7, 0);
				a.setBeginTime(start.getTime());
				Calendar end = Calendar.getInstance();
				end.clear();
				end.set(2016, 9, 24, 9, 0);
				a.setEndTime(end.getTime());
				r.addActivity(a);
				rl.add(r);
				return rl;
			}
			
			@Override
			protected int getConfiguredGridH() {
				return 10;
			}

			@Override
			protected boolean getConfiguredLabelVisible() {
				return false;
			}			
		}
	}

I get an "internal UI error (code T6)" and the browser console (chrome) shows

application-all-bb337778.min.js:9 Uncaught TypeError: Cannot read property 'children' of undefined

at the following code line

var scaleItemsLarge=this.planner.$timelineLarge.children(".scale-item")

It seems that $timelineLarge is undefined at that time.
Any ideas on this? Do I have to add something to make this work?

Hmmm... do I have bad luck? Does anyone face the same phenomenon?
If I am the only one I believe something is wrong with my test code.
No hints for me?

Sorry for the delay, we were busy at the EclipseCon Europe (and the days before that preparing the event). I have the same error with the code snippet you have provided... I have compared it with some code I have developed a long time ago.

The error disappears when I set the display mode of the planner during field initialization. I have also added "loadResources()" to load the data.

@Order(101000)
public class TrainerPlannerField extends AbstractPlannerField<TrainerPlannerField.Planner, Long, Long> {
	
	@Override
	protected void execInitField() {
		getPlanner().setDisplayMode(ICalendarDisplayMode.WEEK);
		loadResources();
	}

	//... rest of the implementation

The planner field probably deserves some documentation and some updated example, because the field is not easy to use.

Related discussion (old topic):
Swing PlannerField

I will be offline until the middle of next week.

Thanks for the reply! EclipseCon of course... that wasn't on my mind any more. Hope it was a successful conference for you.

I just tried your suggestion and it worked. But as soon as I tried to switch to ICalendarDisplayMode.MONTH in execInitField() (since I wanted only to offer display mode 'month' and 'year') the problem occurred again. Playing around with some permutations I figured out that after having removed my override of getConfiguredDisplayMode() everything works fine.

A sample and some docs would be great but so far I am glad that I can go on with my implementation.

Thanks a lot for your help!

Good day,

I have followed the suggestions in this thread to get the PlannerField to work. If someone could indicate which children the error is referring to because it seems like it is meant to be the Actvities/Resources but I have added those in the execLoadResources and I am not sure what other field I am meant to declare as an inner class of Planner since I have tried the TableField when I saw the Swing PlannerField discussion but TableField also did not work.

@Order(1250)
			public class ActivityPlannerField extends AbstractPlannerField<ActivityPlanner, Long, Long> {

				@Override
				protected boolean getConfiguredLabelVisible() {
					return false;
				}

				@Override
				protected int getConfiguredGridW() {
					return FULL_WIDTH;
				}
				
				
				@Override
				protected void execInitField() {
					
					
					getPlanner().setDisplayMode(IPlannerDisplayMode.CALENDAR_WEEK);
					loadResources();
				}
				
				
				
				
				@Override
				protected List<Resource<Long>> execLoadResources() {
					
					System.out.println("Planner load resources");
					
					ProjectPlan projectPlan = BEANS.get(IPlanningService.class).retrieveProjectPlan(1L);
					
					List<Resource<Long>> resources = new ArrayList<>();
					
					try {
						Resource<Long> resource = new Resource<>(1L, "DEV1");
						
						for (ProjectActivity projectActivity : projectPlan.getActivities()) {
							
							Activity<Long, Long> activity = new Activity<>(projectActivity.getProperties());
							resource.addActivity(activity);
						}
						
						resources.add(resource);
						
					} catch (Exception e) {
						e.printStackTrace();
					}
					
					System.out.println("Planner load resources " + resources.size());
					return resources;
				}
				
				
				
				public class ActivityPlanner extends AbstractPlanner<Long, Long> {

					
					@Override
					protected Set<Integer> getConfiguredAvailableDisplayModes() {
						return CollectionUtility.hashSet(
								IPlannerDisplayMode.WEEK,
								IPlannerDisplayMode.CALENDAR_WEEK,
								IPlannerDisplayMode.MONTH);
					}
					
					
					@Override
					protected boolean getConfiguredActivitySelectable() {
						return true;
					}
					
					@Order(1000)
					public class TestMenu extends AbstractMenu  {
						@Override
						protected String getConfiguredText() {
							return TEXTS.get("MyNlsKey");
						}

						@Override
						protected Set<? extends IMenuType> getConfiguredMenuTypes() {
							return CollectionUtility.hashSet();
						}

						@Override
						protected void execAction() {
						}
					}
				}
			}

Your code looks alright, no need to mix tables and planners. The "children" mentioned in the error message are releated to DOM elements in the browser.

Unfortunately, the implementation seems to be quite picky about the correct property values. In your case, the property "viewRange" is not initialized, which the planner doesn't like. Apparently the viewRange would be automatically calculated when you set the display mode. Unfortunately, CALENDAR_WEEK is already the default value, so this calculation is not triggered. The easiest fix would therefore be to initialize the display mode to some other value first.

      @Override
      protected void execInitField() {
        getPlanner().setDisplayMode(0); // <--
        getPlanner().setDisplayMode(IPlannerDisplayMode.CALENDAR_WEEK);
        loadResources();
      }

I'm not an expert on the Planner widget, but this seems to do the trick. If someone knows of a better way, please let us know.

Regards,
Beat
