thats my fragment.. on table1 there is a Searchfield and it works.. like it should.
on my second table on table2 this does not work..
and i dont really know why.. the one is a json model the other not.. maybe thats why?
controller
onFilterAllOrder: function (oEvent) {
var oTable = this.byId("table1");
var searchText = oEvent.getParameters().newValue;
var filters = [];
if (searchText.trim() != '') {
var filter1 = new sap.ui.model.Filter({
path: "Ktext",
operator: sap.ui.model.FilterOperator.Contains,
value1: searchText
});
filters = [filter1];
var finalFilter = new sap.ui.model.Filter({
filters: filters,
and: false
});
oTable.getBinding("rows").filter(finalFilter, sap.ui.model.FilterType.Application);
} else {
oTable.getBinding("rows").filter([], sap.ui.model.FilterType.Application);
}
},
onFilterSelectedOrder: function (oEvent) {
var oTable = this.byId("table2");
var searchText = oEvent.getParameters().newValue;
var filters = [];
if (searchText.trim() != '') {
var filter1 = new sap.ui.model.Filter({
path: "Ktext",
operator: sap.ui.model.FilterOperator.Contains,
value1: searchText
});
filters = [filter1];
var finalFilter = new sap.ui.model.Filter({
filters: filters,
and: false
});
oTable.getBinding("rows").filter(finalFilter, sap.ui.model.FilterType.Application);
} else {
oTable.getBinding("rows").filter([], sap.ui.model.FilterType.Application);
}
}
so maybe i dont see something? or make some mistakes? so i try everything.. but nothing work.. i mean it should be the same as the one before but somehow it dont work...

Answer 1

If the latter is a OData model, the filtering would be done against the service if you have not set the operation mode to client. In this case, a request against the backend is made and if that service does ignore $filter, you'll see no change.
Check the network tab and look if a request is made.
