ng-template [NgForOf] return undefined value

Question

I have the next problem: construction

<p-dataTable [value]="listOfAddresses" [expandableRows]="true" [expandedRows]="listOfAddresses" ">
    <p-column>
        <ng-template let-item="rowData" let-i="rowIndex" pTemplate="body">
                {{i+1}}
        </ng-template>
    </p-column>
    <p-column >
         <ng-template ngFor let-item [ngForOf]="listOfOriginalAddresses" pTemplate="body">
             {{item.Street + " " + item.City}}   
         </ng-template>
    </p-column>
</p-table>

Returns undefined values for item.Street and item.City Strange because if I use

<p-column >
   <ng-template pTemplate="body">
      <div *ngFor="let item of listOfOriginalAddresses">
          {{item.Street + " " + item.City}}   
     </div>
   </ng-template>
</p-column>

I have all required values but all the list in the row. What is the problem? Thanks in advance

Answer 1

Solved but not with using of ngFor.

I create pipe:

 transform(value: any): any {
        let item = value;
        return (item.Street + " " + item.Country);
    }

Furthermore, data don't change according to the edition in the fields with parced address, what solved another headacke.
