and this is my controller, check i have a fuction for each element, input, search field an submit

		onSearch : function(oEvt) {
			// build filter array
			var aFilter = [];
			// fetch event parameter
			var sQuery =  oEvt.getSource().getValue();
			
			if(sQuery && sQuery.length > 0) {
				var filter = new Filter("RESPONSABLE", sap.ui.model.FilterOperator.Contains, sQuery);
				aFilter.push(filter);
			}
			
			var list = this.getView().byId("lista");
			var binding = list.getBinding("items");
			binding.filter(aFilter, "Application");
		},
		onSearchs : function(oEvent) {
			// build filter array
			var aFilter = [];
			// fetch event parameter
			var sQuery = oEvent.getParameter("value");
			// Regresa la lista
			var oList = this.getView().byId("lista");
			// get binding for aggregation 'items'
			var oBinding = oList.getBinding("items");


			if (sQuery) {
				aFilter.push(new Filter("RESPONSABLE", FilterOperator.Contains, sQuery));
			}
			// apply filter. an empty filter array will show all items
			oBinding.filter(aFilter);
		},
		
		onSearch : function(oEvent) {
			// build filter array
			var aFilter = [];
			// fetch event parameter
			var sQuery = this.byId('cat').getValue();
			// Regresa la lista
			var oList = this.getView().byId("lista");
			// get binding for aggregation 'items'
			var oBinding = oList.getBinding("items");


			if (sQuery) {
				aFilter.push(new Filter("RESPONSABLE", FilterOperator.Contains, sQuery));
			}
			// apply filter. an empty filter array will show all items
			oBinding.filter(aFilter);
		}

"RESPONSABLE" it's the property of my entity of the odata , yes, in capital so, can you see something that i'm not ? and also i don't get any error

if you bind to odata directly, the filtering has to be implemented in your odata code. check with your odata developer if he has done the job or not.

i'm the odata developer, fiori anba little basis jejeje but i'll check be cause i don't know if i check those optiones to filter

[junwu]

then you should be very clear, have you done anything in your code to do the filtering?

[naotoxxx]
