Get method of HtmlPanelGrid is not getting called

Question

Hi,
I'm creating components dynamically.
I have a dropdown. Based on the selection of dropdown, the corresponding values are displayed and the get method of HtmlPanelGrid should be called.
First time the panel grid getmethod is getting called. But when i change the value of drop down, panel grid get method is not getting called and its not rendering.
This is the code:
JSF:
Drop Down
<h:panelGroup>
<t:selectOneMenu id="selectProjectTypes" onchange="sbmitform();" immediate="true" valueChangeListener="#{ProjectController.projectTypeChanged}" value="#{ProjectController.project.selectProjectTypes}">
<f:selectItem itemLabel="--------------------" itemValue="-1"/>
<f:selectItems value="#{ProjectController.projectTypesList}"/>
</t:selectOneMenu>
</h:panelGroup>
Panel Grid
<h:panelGrid columns="2" rendered="#{ProjectController.projects}" id="test" binding="#{ProjectController.defaultValues}" columnClasses="hunderadfifty" cellpadding="5" />
Controller:
public void projectTypeChanged(ValueChangeEvent event) throws AbortProcessingException,Exception {
String nodeTypeId = null;
String selectedValue = (String)event.getNewValue();
getSessionCache().addValue("test", 0, "1");
if(selectedValue.equalsIgnoreCase(selectedValue)){
try
// this.getDefaultValues().setRendered(true);
// defaultValues=this.getDefaultValues();
} catch (Exception e)
e.printStackTrace();
FacesContext.getCurrentInstance().renderResponse();
Panel Grid Method
*public HtmlPanelGrid getDefaultValues() throws Exception {*
String devlues = (String)getSessionCache().getValue("test");
Application app = FacesContext.getCurrentInstance().getApplication();
labelList = nodeTypeFieldsService.getFixedFields(this.getRpUserData(), this.getAuthUser());
HtmlPanelGrid panelGrid = (HtmlPanelGrid)app.createComponent(HtmlPanelGrid.COMPONENT_TYPE);
for(int i = 0; i<labelList.size(); i++)
HtmlOutputText heading = (HtmlOutputText)app.createComponent(HtmlOutputText.COMPONENT_TYPE);
HtmlPanelGroup panelGroup = (HtmlPanelGroup)app.createComponent(HtmlPanelGroup.COMPONENT_TYPE);
HtmlInputText inputText = (HtmlInputText)app.createComponent(HtmlInputText.COMPONENT_TYPE);
String fieldHeading =((ProjectField)labelList.get(i)).getFieldHeading();
int fieldLength = ((ProjectField)labelList.get(i)).getFieldLength();
String fieldDescription = ((ProjectField)labelList.get(i)).getFieldDescription();
String fieldType = ((ProjectField)labelList.get(i)).getFieldType();
inputText.setValueBinding("value", (ValueBinding) app.createValueBinding("#{ProjectController.newProj}"));
if(fieldType.equalsIgnoreCase("3"))
heading.setValue(fieldHeading);
heading.setTitle(fieldDescription);
inputText.setMaxlength(fieldLength);
inputText.setSize(fieldLength);
UIRDDialog dialog = (UIRDDialog)app.createComponent(UIRDDialog.COMPONENT_TYPE);
dialog.setTitle("Object Type Dialog");
dialog.setHeight("370");
dialog.setWidth("350");
dialog.setUrl("searchObjectTypeDialog.jsf");
UIRDIconButton iconButton = (UIRDIconButton)app.createComponent(UIRDIconButton.COMPONENT_TYPE);
iconButton.setType("button");
iconButton.setTitle("Search for Object Types");
iconButton.setIcon("/image/icon/portalicon_search.gif");
iconButton.setActivateDialog("searchObjectTypeDialog");
panelGroup.getChildren().add(inputText);
panelGroup.getChildren().add(iconButton);
panelGroup.getChildren().add(dialog);
panelGrid.getChildren().add(panelGroup);
}else
panelGroup.getChildren().add(inputText);
heading.setValue(fieldHeading);
inputText.setMaxlength(fieldLength);
inputText.setSize(fieldLength);
heading.setTitle(fieldDescription);
panelGrid.getChildren().add(panelGroup);
panelGrid.getChildren().add(heading);
panelGrid.getChildren().add(panelGroup);
HtmlCommandButton createButton = (HtmlCommandButton)app.createComponent(HtmlCommandButton.COMPONENT_TYPE);
createButton.setId("create");
createButton.setTitle("Create");
createButton.setValue("Skapa");
createButton.setAction(app.createMethodBinding("#{ProjectController.saveProject}", null));
HtmlCommandButton backButton = (HtmlCommandButton)app.createComponent(HtmlCommandButton.COMPONENT_TYPE);
backButton.setId("back");
backButton.setTitle("Cancel");
backButton.setValue("Avbryt");
backButton.setAction(app.createMethodBinding("#{ProjectController.cancel}", null));
panelGrid.getChildren().add(createButton);
panelGrid.getChildren().add(backButton);
return panelGrid;
/* } else {
return null;

Hi,
I'm having the exact same problem, and it's freaking me out!!! The setGridPanel method is always called but not the getGridPanel. This one is only called the first time the page is rendered, and when I change a drodpdownlist it never gets the gridPanel again! I'm using an HtmlPanelGrid. Anyone can help please?
Thanks in advance,
Raquel
