Programatically Hiding ADF component

Question

Hi,
I have a requirement for which i am hiding a adf component using render=false or visible=false and move other existing component in screen to the place of hidden component. The screen is codded as below,
<?xml version='1.0' encoding='UTF-8'?>
<jsp:root xmlns:jsp="http://java.sun.com/JSP/Page" version="2.1"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:af="http://xmlns.oracle.com/adf/faces/rich">
<jsp:directive.page contentType="text/html;charset=UTF-8"/>
<f:view>
<af:document id="d1">
<af:form id="f1">
<af:panelGroupLayout id="pgl1" layout="scroll">
<af:panelBox text="PanelBox1" id="pb1">
<f:facet name="toolbar"/>
<af:panelFormLayout id="pfl1" rows="1" maxColumns="2"
binding="#{StartPageBean.pfl1}">
<f:facet name="footer"/>
<af:outputText value="1" id="ot1" binding="#{StartPageBean.ot1}"/>
<af:outputText value="2" id="ot2" binding="#{StartPageBean.ot2}"/>
</af:panelFormLayout>
<af:panelFormLayout id="pfl2" rows="1" maxColumns="2"
binding="#{StartPageBean.pfl2}">
<f:facet name="footer"/>
<af:outputText value="3" id="ot3" binding="#{StartPageBean.ot3}"/>
<af:outputText value="4" id="ot4" binding="#{StartPageBean.ot4}"/>
</af:panelFormLayout>
<af:panelFormLayout id="pfl3" rows="1" maxColumns="2"
binding="#{StartPageBean.pfl3}">
<f:facet name="footer"/>
<af:outputText value="5" id="ot5" binding="#{StartPageBean.ot5}"/>
<af:outputText value="6" id="ot6" binding="#{StartPageBean.ot6}"/>
</af:panelFormLayout>
</af:panelBox>
</af:panelGroupLayout>
<af:commandToolbarButton text="commandToolbarButton 1" id="ctb1"
action="#{StartPageBean.hideComponents}"/>
</af:form>
</af:document>
</f:view>
</jsp:root>
This code render the out as,
1 2
3 4
5 6
As we can see that we have PanleGroupLayout than a PanelBox and than all the PanleGroupLayout with 1 row and 2 column.
Now if i make ot2 an ot3 as hidden using render false the output comes as below,
1
4
5 6
If i make ot2 and ot3 as hidden using visible false the output comes as,
1
4
5 6
can we get the output as
1 4
5 6
by using either of the approach? or is there any other approach to achiecve the same.
Let me know if some more information is required

Hi,
I have created an ADF tree using VO. its being displayed with several nodes (Drag and drop fo data control). Now I want to add dynamically created links into the created tree nodes. how to do that from inside my backing bean code.
for (int i = 0; i < assignedAuditLinksCount; i++) {
HashMap auditInfoMap = assignedAuditList.get(i);
RichCommandImageLink auditInfo = new RichCommandImageLink();
RichSpacer auditLinkSpacer = new RichSpacer();
auditInfo.setText(auditInfoMap.get(AuditOperationsConstants.AUDITID).toString());
auditInfo.setIcon("/images/navbullet.png");
String actionEL =
"#{backingBeanScope.backing_fragments_PerformAudit.setAuditInfo_action}";
MethodExpression action = actionMethodExpression(actionEL);
auditInfo.setId("AuditId" + (i + 1));
auditInfo.setActionExpression(action);
auditInfo.addActionListener(new PerformAuditActionListener());
auditInfo.setVisible(true);
auditInfo.setImmediate(true);
auditInfo.setInlineStyle("text-decoration:underline;");
auditLinkSpacer.setHeight("0");
auditLinkSpacer.setWidth("10");
How to add these auditInfo links in my tree nodes created using VO.
