so, you do
this.getView().bindElement("/DETAILSSet('VALUE1')");
...
<Text id="text1" maxLines="0" text="{TestResult}">
and TestResult is from DETAILSSet and when you test
/sap/opu/odata/sap/ZGW_RFC_DEST_DETAILS_SRV_01/detailset('VALUE1')
in browser it returns data
but that text is not getting popupated and you see 2 red requests: DETAILSSET and DETAILS in console
do you code or bind to DETAILS anywhere in th code?
