Binding Path for nested array in SAPUI5 Table

[former_member688076]

I am trying to bind a nested array to the SAPUI5 table.

Json Model:
{
"Departments": [
    {
        "ID": "1",
        "Name": "Oil and Gas",
        "Employees": [
            {
                "ID": "12345",
                "LastName": "Tom"
            },
            {
                "ID": "678",
                "LastName": "Jerry",
            }
        ]
    },
    {
        "ID": "2",
        "Name": "Gasoline",
        "Employees": [
            {
                "ID": "21",
                "LastName": "Donald"
            },
            {
                "ID": "22",
                "LastName": "duck"
            }
        ]
    }
]
}

I am using SAPUI5 table:

 <Table 
    items="{path:'oDataItem>/Departments/Employees'}"                                       
    width="auto"
    fixedLayout="false" 
    mode="MultiSelect" >
    <columns>
        <Column width="auto">
            <Text text="LastName of Employee" />
        </Column>
     </columns>
         <items>
             <ColumnListItem>
                 <cells>
                      <Input editable="true" textAlign="Left" type="Text" change="onNameTextChange" width="15em" value="{path:'oDataItem>LastName'}" />
                 </cells>
            </ColumnListItem>
         </items>           
 </Table>

Above databinding path is not returning any data. 
Can i fetch lastName by XML databinding? If yes, than how i fetch last name?

Thanks

I think you can use element binding and relative binding, no need to create different model.

> /Departments/Employees

Which list of employees should the table pick from the departments list? The table cannot know.

The users, however, know which employees from which departments they want to see. Let them decide by allowing them to pick a department first, and then you can bind the corresponding employee list to the table.

I.e. either a tree-like control or a set of two list controls (one for departments, one for the employee list) is needed in your case. Here is an example: https://embed.plnkr.co/fVCzodmvWzieh2LH

    items="{path:'oDataItem>/Departments/0/Employees'}"  
you can change to other index value. I didn't try in my system, hopefully it works.

@Jun Wu : Ur solution always provide index 0. It is not dynamic. I did some research, i came to conclusion that data binding in XML wont help in my scenario. I need to build my own json and bind it

gopalp, yes you need to manipulate the data and build your structure for your scenario
