SAPUI5: extend oData model at frontend

[Former Member]

Hi,

I ran into the following problem: I bind an oDataModel to a TableSelectDialog and I would like to add a new column (property) to the table what is not included by the oData service. So when the user selected some of the records and set the "new" property and "Confirm" the TableSelectDialog, I would like to merge the oData model's record with the new property and create a new JSONModel.

For example, there is an oDataModel with P1, P2, P3 property, a TableSelectDialog with C1, C2, C3, C4 columns, I bind P1-C1, P2-C2, P3-C3. When I confirm the TableSelectDialog I would like to create a new record to a JSONModel with properties Q1, Q2, Q3, Q4, where Q1=C1-P1, Q2=C2-P2, Q3=C3-P3, Q4=C4.

I already tried to bind the new JSONModel to the TableSelectDialog too, but in this way only one record created and bound for the all row (so when I set the C4 column in one row, the new value applied to the all row).

Is there any solution for? I know there is workaround like create a new "blank" property for the oDataModel's service and use it, but I would like to implement a correct solution.

Thanks,
