getItems() method for table returns up to 20 rows - sapui5

Question

I have a report table that is populated in three different ways, depending on selection filters. At the end of the called report I use the "updateFinished" event to loop through the table entries, paint them zebra style and paint last summary line pink.
SAPUI5 Application version is 1.44.12
this.oStsTable = this.getView().byId("statusReportTable");
this.oStsTable.attachEventOnce("updateFinished", function(oEv) {
var aItems = oEv.getSource().getItems();
if (aItems && aItems.length > 0) {
for (var i = 0; i < aItems.length; i++) {
if (i === aItems.length - 1) {
aItems[i].addStyleClass("pinkBackground");
} else {
var even = i % 2;
if (even !== 0 && i < aItems.length) {
aItems[i].addStyleClass("cyanBackground");
}
}
}
}
});
this.byId("statusReportTable").getBinding("items").filter(oTableSearchState);
With the data available, I get back 3 datasets. 7 for case 1, 7 for case 2 and 23 for case 3. With the first two cases everything is OK. Problem is with case 3 (23 records). Debugging on the back-end, I see 23. When table appears, I see again 23. But the getItems() method within "updateFinished" event sees only 20 (!). As result of it (yes, guessed right), line 20 goes pink and the remaining lines without color as loop exits.
Rings any bells?

Answer 1

If you are only trying to add a zebra style with a different color in the last row, I recommend doing that only with CSS in your app like below.
table tr:nth-child(even) {
background-color: green;
}
table tr:nth-child(odd) {
background-color: red;
}
table tr:last-of-type {
background-color: yellow;
}

If you only need to alternate the row colors on your sap.m.Table then I would recommend you to set the property alternateRowColors to true.
<Table id="idProductsTable"
alternateRowColors="true"
items="{ path: '/ProductCollection' }">
<headerToolbar>
<Toolbar>
<Title text="Products"/>
</Toolbar>
</headerToolbar>
<columns>
<Column>
<Text text="Product" />
</Column>
<Column>
<Text text="Supplier" />
</Column>
</columns>
<items>
<ColumnListItem>
<cells>
<ObjectIdentifier title="{Name}" text="{ProductId}"/>
<Text text="{SupplierName}" />
</cells>
</ColumnListItem>
</items>
</Table>
Note: This property can only be used with the Belize and Belize Deep themes. Alternate row coloring is not available for the High Contrast Black/White themes.
