I'm developing software for 40+ years but I'm absolutely new to SAP UI5, so maybe this is very basic or a trivial problem but half a day of searching the internet brought no results:
In a Master-Detail View (defined in xml) I want to display a list of items with growing=true, growingThreshold=50 and growingScrollToLoad=false as a List.
In principle it got everything working OK now. But there is a tiny glitch, not essential, more in the category of a "nice to have":
All the examples I've seen so far show something like "[ 50 / 107 ]" below the "More" button. But in my program it is missing. I'm very sure the reason is __count is not included in the response sent from the Odata-Service implementation.
Testing directly with the SAP Gateway Service Builder (/SEGW) shows to include the count in the response $inlinecount=allpages needs to be appended to the service URI. And here it works fine - once I add this to the URI the count is included, when I leave it out or set it to none there is no count included.
Therefore the problem seems not to be in the service implementation. (At least the __count field is present or not present as expected. And I assume this is what enables the "[ # / # ]" indicator.)
When the request is then sent from the controller (implemented in JavaScript) this part is not added to the service URI, despite the OData-Model is created with defaultCountMode: "sap.ui.model.odata.CountMode.InlineRepeat". On the "Network" page of Chrome's developer tools I don't see the $inlinecount=allpages appended and also the "[ 50 / 107 ]" (or whatever is appropriate) is not shown with the "More" button.
I checked with the Chrome developer tools immediately after creating the Odata-Model if my setting in the OData-Model takes effect – and it does. And I checked once more before a request is made based on this OData-Model – and it is still there.
My only idea now is it might have something to do with the fact the request originates from the XML-view (ie. the JavaScript code created on behalf of it) and it might be using a different Odata model in which that option is not set.
How can I test for this?
Any other ideas?
Maybe an internationalization issue? (The trigger-text for displaying more entries is set to "Weiter" in German language. Maybe also the "[ # / # ]" parts needs to be re-defined elsewhere too?
