Hi,
I am learning to create fiori apps with the hana cloud platform. I have created a fiori master detail app and specified my OData model as well as mock data ( I don't have a backend service).
The app is pretty simple, the master contains a set of elements for which the details are shown in the Detail view in two tabs. One tab contains general information and the second contains a table. This second tab's count property must contain the table's number of rows.
What I have tried so far is to get the number of rows (Detail.controller.js):
this.byId("__table0").getItems().length and put it in the tab filter's count property:
this.byId("iconTabFilter2").setCount(this.byId("__table0").getItems().length);This piece of code does the trick... but I don't know where to put it. I literally put it at the end of every function in the controller but when i test, the result is wrong.
Example: I have two elements in the master, the first element's table has 4 rows and the second has 0. Both tabs show 0 as their count. When I used a console log, here's what I get (I put the log at the end of every function in the controller. The number on the left is the number of elements in the table) :
When the app first starts, the first master element is is selected.
0 getEventBus 0 getRouter 0 onInit 0 onRouteMatched 0 onRouteMatched 0 getEventBus 0 fireDetailChanged 0 fireDetailChanged 0 getEventBus 0 onMasterLoaded
When I select the second element in the master:
4 onRouteMatched 4 getEventBus 4 fireDetailChanged 4 fireDetailChanged 0 getEventBus 0 onRouteMatched
When I go back to selecting the first element in the master:
0 onRouteMatched 0 getEventBus 0 fireDetailChanged 0 fireDetailChanged 0 getEventBus 0 onRouteMatched
