How to make selected and active a child row of a treeTable?

Question

Hello,
I am inserting a new child row into a af:treeTable, disclosing it, but I can't figure out how to make it selected and active so the focus of the user to go on it.
Jdeveloper version 11.1.2.3.0
This is how I am inserting the child node:
public void createLocation(RowIterator ri, Key selectedNodeKey) {
        final String locationCategoryViewDef = "model.views.LocationCategoryView";
        if (ri != null && selectedNodeKey != null) {
            Row[] found = ri.findByKey(selectedNodeKey, 1);
            if (found != null && found.length == 1) {
                Row foundRow = found[0];
                String nodeDefname = foundRow.getStructureDef().getDefFullName();
                RowSet parents = (RowSet)foundRow.getAttribute("LocationView");
                Row childrow = parents.createRow();
                //hardcoded locationId
                childrow.setAttribute("LocationId", 434558);
                parents.insertRow(childrow);
}  And this is the treeTable:
<af:treeTable value="#{bindings.LocationCategoryView2.treeModel}" var="node" varStatus="vaarr"
              partialTriggers="gaga gag4a ga4a"
              selectionListener="#{bindings.LocationCategoryView2.treeModel.makeCurrent}"
              displayRow="selected" rowSelection="single" id="tt1" editingMode="clickToEdit"
              horizontalGridVisible="true" binding="#{pageFlowScope.treeTableBean.sampleTreeTable}">
    <f:facet name="nodeStamp">
        <af:column id="c5" width="15">
            <af:outputText value="#{node}" inlineStyle="display:none" id="ot1"/>
        </af:column>
    </f:facet>
    <f:facet name="pathStamp">
        <af:inputText value="#{node}" id="ot2"/>
    </f:facet>
    <af:column id="c2" headerText="Location CategoryName">
        <af:inputText value="#{node.LocationCategoryName}" inlineStyle="font-weight:900" id="ot45"/>
    </af:column>
    <af:column id="c6" headerText="Location CATID">
        <af:inputText value="#{node.LocationCategoryId}" inlineStyle="font-weight:900" id="ot6"/>
    </af:column>
    <af:column id="cgg2" headerText="Var INDEx">
        <af:outputText value="#{vaarr.index}"/>
    </af:column>
    <af:column id="c1" headerText="Location Name">
        <af:inputText value="#{node.LocationName}" id="ot3"/>
    </af:column>
    <af:column>
        <af:panelGroupLayout layout="vertical">
            <af:commandLink id="gaga" text="addLocation" inlineStyle="color:red"
                            action="#{pageFlowScope.treeTableBean.createChildren}"
                            rendered="#{node.LocationId == null}" partialSubmit="true"/>
            <af:commandLink id="gag4a" text="delete category" inlineStyle="color:blue"
                            partialSubmit="true" rendered="#{node.LocationId == null}"
                            action="#{pageFlowScope.treeTableBean.deleteChildRow}"/>
            <af:commandLink id="ga4a" text="delete location" inlineStyle="color:green"
                            partialSubmit="true" rendered="#{node.LocationId != null}"
                            action="#{pageFlowScope.treeTableBean.deleteChildRow}"/>
        </af:panelGroupLayout>
    </af:column>
</af:treeTable>

Yes I did now but nothing changes. The current, selected and active row is still the parent node...
Even I am adding AdfFacesContext.getCurrentInstance().addPartialTarget(this.sampleTreeTable); for just in case..
