Dvt:map Selection Iterator

Question

This is a question of urgency. It is holding up a deliverable.
The dvt:mapPointTheme selectionListener property does not seem to fill the Iterator with the selected data point information any longer. This code used to work in TP4.
Here is the .jspx code:
<dvt:mapToolbar mapId="map1"/>
<dvt:map id="map1" startingX="-98.0" mapServerConfigId="mapConfig1"
baseMapName="ELOCATION_MERCATOR.WORLD_MAP" mapZoom="3"
inlineStyle="width:100%; height:400px;" startingY="39.0">
<dvt:mapPointTheme id="mapPointTheme1"
value="#{bindings.Load.geoMapModel}"
selectionListener="#{mapBacking.processSelection}">
<dvt:mapPointStyleItem imageURL="/loadUnselected.png"
selectedImageURL="/loadSelected.png"
shortLabel="Customer Load"
isDefault="true"/>
</dvt:mapPointTheme>
</dvt:map>
Here is the binding pageDef:
<mapTheme IterBinding="fetchMoreLoadsIterator" id="Load"
xmlns="http://xmlns.oracle.com/adfm/dvt">
<mapThemeDataMap mapThemeType="point">
<item type="us_form_2" street="street" city="city" state="state"
zipCode="zipcode" label="cityState"/>
<item type="data" value="customer" label="Customer"/>
</mapThemeDataMap>
</mapTheme>
Here is the "mapBacking" backing bean:
public void processSelection(MapSelectionEvent E) {
if (E.getSelectionMode().equals("Unselect")) return;
Iterator I= E.getIterator();
while (I.hasNext()) {
DataContent DT = (DataContent)I.next();
String S= DT.getLocationName();
When the user chooses the "arrow" icon on the map toolBar, then left click on the data point on the map:
1. The icon changes appearance from "loadSelected.png" to "loadUnselected.png" correctly.
2. The processSelection(mapSelectionEvent E) backing bean method gets called. But the Iterator is empty.
When the user uses a selection shape (circle, square..) on the toolbar, then draws a shape around several of the data points on the map:
1. The icons changes appearance from "loadSelected.png" to "loadUnselected.png" correctly.
2. The processSelection(mapSelectionEvent E) backing bean method gets called. But the Iterator is still empty.
This code used to work. We are up against an extremely tight deadline. Is this an dvt:map bug, or is it just something simple we are overlooking.
Please, we need help ASAP. Thank you gratefully.

Answer 1

I just tried the following with JDeveloper 11g update 2: Build JDEVADF_MAIN.BOXER_GENERIC_090328.0229.5205
Create an ADF BC EO/VO/AM based on a table with spatial data.
Create a page with panelStretchLayout
Drag the data control to the start area as a Form
Drag the data control as to the center as a Map
Define PartialPage rendering so the map updates the form.
Run the page - clicking points in the map updates the Form.
Which build are you using?
Does your ADF BC VO has an attribute marked as key?
