10/01/2016, 3:25 PMI am starting to realize what I dont like of any of the solutions I have seen sofar - r
ron
10/01/2016, 3:25 PMbut I am trying to find the right words to describe it - r
ron
10/01/2016, 3:30 PMit feels a bit bulky both the original solution where you have two lists mirroring a part of eachother - r
ron
10/01/2016, 3:31 PMand this solution where you have two properties who basically contain two lists that partly mirror eachother - r
ron
10/01/2016, 3:31 PMI was looking at doing it withFilteredList - r
ron
10/01/2016, 3:31 PMas FilteredList is at least made for it but I cant get it to work decently - c
carlw
10/01/2016, 3:32 PMYour version seems to be missing a class I created a week ago called TodoItemModel. This component exposes three properties for binding: items, viewableItems, and filter. - c
carlw
10/01/2016, 3:32 PMthe UI interacts with this class via add() and remove() functions - c
carlw
10/01/2016, 3:32 PMand juggles the two lists - c
carlw
10/01/2016, 3:32 PMwe need one list for the comprehensive items and also for the "# items remaining" label - c
carlw
10/01/2016, 3:33 PMand the second list for the viewable (filter) items - r
ron
10/01/2016, 3:33 PMis the TodoItemModel not just another way of saying “controller”? - r
ron
10/01/2016, 3:33 PMI saw the TodoItemModel and went like “thats a controller we already have one 😉 - r
ron
10/01/2016, 3:33 PMwhat I tried to do - c
carlw
10/01/2016, 3:34 PMI'd go with model since there is no layer "underneath" TodoItemModel. We have a RAM-based datasource that doesn't persist. - r
ron
10/01/2016, 3:34 PMCopy codeval viewList = FilteredList(todoItemModel, {item -> true}) ` - c
carlw
10/01/2016, 3:34 PMIf you need a Kotlin break, I put up this Java article on the filtering - c
carlw
10/01/2016, 3:34 PM - r
ron
10/01/2016, 3:35 PMthe views dont need to know if its rambased or not? - c
carlw
10/01/2016, 3:35 PMNo, the views just get add(), remove(), filter, items, and viewableItems - c
carlw
10/01/2016, 3:36 PMif add() asynchronously makes a RESTful call, the UI doesn't know about it - r
ron
10/01/2016, 3:36 PMhmmz this is a semantic thing I would call the model a repository - c
carlw
10/01/2016, 3:37 PMi was using "model" b/c that's the term used in the other examples from lestard - c
carlw
10/01/2016, 3:37 PMyou could also strip "model" out entirely and just call it TodoItems - c
carlw
10/01/2016, 3:39 PMfor the FilteredList(), how does the ListView get updated? New FilteredList object added with a change in ToggleButton? - r
ron
10/01/2016, 4:13 PMthat is what I was trying to get to work - r
ron
10/01/2016, 4:13 PMif you just put the FilteredList as the items for the listview it works, but I have to play with the predicates - r
ron
10/01/2016, 4:13 PMif you use a filteredlist you dont have to add it to it - r
ron
10/01/2016, 4:44 PMbut I even checked the properties page on the wiki and the syntax is correct
