SAPUI5 complex binding

[former_member197112]

Hi all,

I face a binding problem, means no data is shown. My view contains a sap.m.table. One of the columns is type of sap.m.MultiComboBox and defined this way

var selectOwners= new sap.m.MultiComboBox("ownersTmpl-Group",{ selectedKeys: "{table>owner_id}", enabled: "{table>edit}", templateShareable : true, items:{ path:'table>owner_name', templateShareable: true, template: new sap.ui.core.Item({ key: "{id}", text: "{short} ( {long} )" }) } });

the model instance "table" is is type of json containg an array of object entries of this structure

1. as_rights:true
2. id:144
3. is_owner:true
4. member_id:Array[1]
   1. 0:95
   2. length:1
   3. __proto__:Array[0]
5. member_name:Array[1]
   1. 0:Object
   1. id:95
   2. long:"Peter Ruppert"
   3. short:"d039587"
   4. __proto__:Object
6. length:1
7. __proto__:Array[0]

name:"analysis.aad_maint"

owner_id:Array[1]

1. 0:95
2. length:1
3. __proto__:Array[0]

owner_name:Array[1]

1. 0:Object

1. id:95
2. long:"Peter Ruppert"
3. short:"d039587"
4. __proto__:Object

length:1

__proto__:Array[0]

__proto__:Object

Obviously the binding is wrong since the entries of the drop down box are existing but containing no text.

How solve this?

Any help is appreciated.

best regards

Wolfgang

,

try this,

var selectOwners = new sap.m.MultiComboBox("ownersTmpl-Group", {
    selectedKeys: "{table>owner_id}",
    enabled: "{table>edit}",
    templateShareable: true,
    items: {
        path: 'table>owner_name',
        templateShareable: true,
        template: new sap.ui.core.Item({
            key: "{table>id}",
            text: "{table>short} ( {table>long} )"
        })
    }
});
