SAPUI5 Binding list of comboboxes values from a different json tree than the selectedKey binding

[miroslav_sedlar]

Hello all,
let us assume that we have a json with two trees of values. One tree, let's call it T_DATA contains the information of selected keys for the comboboxes, T_CELLS contain the items for the comboboxes lists.

There would be no problem if the combobox items were in the same tree with the selected key binding, but I can't change the json. Is this data binding possible?

oTable.addColumn(new sap.ui.table.Column({
 label: new sap.m.Label({text: "Example"}),
  template: new sap.m.ComboBox({
   selectedKey: "{SALESORG}",
 items: {
 path: "???",
 template: new sap.ui.core.ListItem({
 key: "{V_KEY}",
 item: "{V_VALUE}"
 })
 }
 })
}));
oTable.bindRows("/T_DATA");

Thanks a lot!

I have made a jsbin example.

This

path: "/T_CELLS/0/T_CELLS/0/T_DDLB",

must be changed.. the first 0 is hardcoded row number and the second 0 means that there can be more comboboxes on the same row.. so the factory function must somehow take into account only those items with the corresponding V_FIELDNAME, but I think I will be able to do this.. The first 0 is somehow impossible for me to solve 😞

thanks!

use factory function...

Bind the table to T_DATA then in the factory function during the template creation access T_CELLS to perform binding to combobox.
