                                                                                  my current code has extension functions that binds to the lifecycle - and I'm trying to understand what is the code change needed to adjust it to archlifecycle and auto-dispose.

                                                                                  I would appreciate some help here - couldn't figure it out from the demo code.

                                                                                  The 2 functions above were replaced by this function:

                                                                                  Note that the return type is now CompletableSubscribeProxy and not Completable so the location of the call in the chain might need to be changed.

                                                                                  I create different scopes:

                                                                                  The ShellViewModel constructs LoginViewModel as it's Active Item. I've also set it up to inherit from IHandle as a test that event publishing is working. It is able to handle that event. I haven't shown any Unsubscribe events in my code for brevity.

                                                                                  public class ShellViewModel : Conductor.Collection.OneActive, IHandle

                                                                                  public class ShellViewModel : Conductor.Collection.OneActive

                                                                                      {

                                                                                          await ActivateItemAsync(_loginViewModel);
                                                                                          // IsActive = false here, therefore the child Screen `_loginViewModel` 
                                                                                          // is also not active. Result is that OnActivateAsync 
                                                                                          // in this view model does not get called.
                                                                                      }
                                                                                  }
                                                                                  

                                                                                  It is directly related to this problem and answer.

                                                                                  That explains why moving it to the constructor solved the problem.

                                                                                  The final solution was to add _eventAggregator.SubscribeOnPublishedThread(this); in both the Constructor AND OnActivateAsync method. This allows me to resubscribe to the event after I navigate away from this viewmodel and come back to it.

                                                                                  Yet, I see several types of icons in Class View:

I've looked through a lot of questions on here about this topic and tried quite a few different things but I can't seem to get it work. I can only get the array to be created and store the values and clear when I click the appropriate button when looking in the console tool.

                                                                                  When the add item button is clicked it should show each element entered on the ID listItemsHolder and the clear button clears the list. I appreciate any help I can get. Code below:

                                                                                    "let list = document.getElementById("listItemHolder");"
                                                                                    

                                                                                    Second you are defining the list but never using it.

                                                                                    function addTo() {
                                                                                    list.append(document.getElementById("listItemInput").value);
                                                                                    }
                                                                                    

                                                                                    This will append to the element another method would be to loop over the array.

                                                                                    I have been looking all over for a correct answer on this but can't seem to get one that works. I am trying to take input for an array that allows a max of 6 entries and does not allow duplicates. My code that I was playing around with only alerts me when I already have duplicates in the array. What would be the correct way to prevent a duplicate value from ever being added then displaying an error stating so?

                                                                                    I need to carry it over to list on the HTML doc but for right now I'm working on not allowing it to add duplicates so I've been using the Console tool

                                                                                    Any help would be much appreciated

                                                                                      So if it is there in the SpriteNode before being added to the array why is it not also in the array? I need to be able to access the values of 'conductor' elsewhere in the code so I can change the variables within.

                                                                                      Does the array also have to be an observable object in some way?

I have double-checked it but it is still wrong. I know it's usually to do with indents, but everything seems to be in order. I'll paste the WHOLE code down there. PS some things have hashtags, and so are not active - they are comments.

                                                                                      I was new to rails 7.0 as I followed the official guide in website, making the sample blog project.

                                                                                      When comes to the delete single post function. Seems my code still fires a GET HTTP request instead of a DELETE request. I only have one controller which is articles_controller.rb

I do see in the routes that while a show is being generated, an index route is not.

                                                                                      Any help would be appreciated. Thanks.

                                                                                      I'm completly stuck as Im new to SSRS.

                                                                                      I have a set of data formed like this :

                                                                                      • A "Selection" of rights concerns several "Companies"
                                                                                      • A "Company" contains several "Conductors"
                                                                                      • A "Selection" is accessible by several "Accessors"

                                                                                      My SQL results look like this :

                                                                                      SELECTION_NAME COMPANY_NAME CONDUCTORS_NAME ACCESSORS_NAME SELECT_A COMPANY_A John Maggie SELECT_A COMPANY_A John Lucy SELECT_A COMPANY_A John Veronica SELECT_A COMPANY_A Bob Maggie SELECT_A COMPANY_A Bob Lucy SELECT_A COMPANY_A Bob Veronica SELECT_A COMPANY_AA Luke Maggie SELECT_A COMPANY_AA Luke Lucy SELECT_A COMPANY_AA Luke Veronica

                                                                                      as you can see, conductors are repeated as many time as there are accessors to the relative Selection.

                                                                                      I would like to have, in my SSRS report, a relatively same structure BUT I want that conductors, and associated accessors, listed each ONCE. And, grouping by Selection > Company.

                                                                                      It could be something like this :

                                                                                      SELECTION_NAME COMPANY_NAME CONDUCTORS_NAME ACCESSORS_NAME SELECT_A COMPANY_A John Maggie Bob Lucy Veronica COMPANY_AA Luke Maggie Lucy Veronica

                                                                                      I tried to create 2 datasets and use LOOKUP but if it list conductors only once, at each line, I got the first accessor repeated, no more lines, no other accessors names..

                                                                                      How can I display conductors in 3rd column, regardless number of accessors, grouping by SELECTION > Company AND only SELECTION accessors in the 4th one regardless conductors and also grouping by SELECTION > Company (even if accessors will be repeated on each companies lines of the same Selection) ?

                                                                                      Is this possible with SSRS ? I'm using Microsoft Visual Studio 2010.

                                                                                      Thank you

                                                                                      You do not need to do anything complicated.

                                                                                      Create a dataset that gives you the table you showed at the start of your question.

                                                                                      Then add a tablix (table) to your report.

                                                                                      There are several ways to create the design but if you start by dragging accessor onto the detail row. Now, under the main design windows you will see a section with Row Groups listed, you will only have one called "Detailed", now you can either drag the Conductor just above the detail row group, or you can right-click the detail row group and add a parent group and select Conductor. Repeat to add row groups for the other two columns.

                                                                                      The SSRS documentation explains this process in more detail

                                                                                      https://docs.microsoft.com/en-us/sql/reporting-services/lesson-6-adding-grouping-and-totals-reporting-services?view=sql-server-ver15

You can also use any IDE and you can run and debug the conductor component as you would do with any other Java program. Best practice is to use a build tool that supports dependency management such as Maven or Gradle. For Maven installation, please refer maven.apache.org. For Gradle installation, please refer gradle.org .
