json - SAPUI5 Combobox JSONModel -

i try bind data combobox, don't solved. can see model (modeldata) , data in model.

could tell me, if structure inside of result (ex_labor) correct is?

            <combobox              items="{modeldata}"             selecteditem="selecteditem"               selectedkey="keyselectedkey"              selecteditemid="idselecteditemid"              id="idcomboboxlabor"             placeholder="datum"              textalign="initial"              textdirection="inherit"              maxwidth="100%"              change="onchangelabordatum"              selectionchange="onselectionchangelabordatum">                 <items>                     <core:item  key="{modeldata>patientid}" text="{modeldata>/patientid}"/>                 </items>             </combobox> 

i put ajax request in init function.

controller: jquery.ajax({ url: aurl, method: 'get', datatype: 'json', contenttype: "application/json", success: function(data, textstatus, jqxhr) {

                // create json model instance                 var omodelcombobox = new sap.ui.model.json.jsonmodel();                  /* // set data model                     result:                     {"ex_labor":{"0":{"patientid":3161,"datum":"2014-12-08t23:00:00.000z"},"1":{    */                 omodelcombobox.setdata(data);                  // set model core                 sap.ui.getcore().setmodel(omodelcombobox, "modeldata");                 var adata = omodelcombobox.getproperty("/ex_labor");                  var omodel1 = new sap.ui.model.json.jsonmodel();             //      omodel1.attachrequestcompleted(function() {                     omodel1.setdata({                         modeldata: adata                     });                     console.error(omodel1);                     console.error(adata);             //  });              } 

result

would helpful, if 1 of me.

you need correct binding of combobox items aggregation:

items="{modeldata>/ex_labor} 

also ex_labor should array.

plus need correct binding of item text property (as mentioned @qualiture):

text="{modeldata>patientid}" 

in general should rethink naming: "modeldata" bad name not clear model contains data, not clear kind of data. furthermore recommended use:

this.getview().setmodel(model, name) 

instead of storing in core.
