View Full Version : onModuleLoad() do not run during portlet first load on liferay 6

13 Oct 2011, 12:55 AM
I would like to write a protlet using GXT and Spring portlet MVC and deploy to liferay portal 6. I can succcessfully install my portlet in liferay, but the onModuleLoad() in GXT seems had not run when the portlet first display on liferay. I must press F5 to refreh the protal page so make onModuleLoad() run.

Does anyone know what's wrong with my code? Please advise. Thanks a lot~

Here is my code and config:
public class Searchcar implements EntryPoint {
private Button clickMeButton;
public void onModuleLoad() {
Window.alert("onModuleLoad! -- 1"); // DEBUG_MSG

RootPanel rootPanel = RootPanel.get("portlet-container");
clickMeButton = new Button();
clickMeButton.setText("Click me!");
clickMeButton.setSize("80px", "30px");

rootPanel.setWidgetPosition(clickMeButton, 5, 5);

clickMeButton.addClickHandler(new ClickHandler(){
public void onClick(ClickEvent event) {
Window.alert("Hello, GWT World!");

JSP to display on portlet:

<link rel="stylesheet" type="text/css" href="/carportlet/ExtGWT/css/gxt-all.css" >
<link rel="stylesheet" type="text/css" href="/carportlet/search_car_.css" >

<div id="portlet-container"></div>
<script type="text/javascript" language="javascript" src="/carportlet/searchcar/searchcar.nocache.js"></script>


<module rename-to='searchcar'>
<inherits name="com.google.gwt.user.User"/>

bean difinition:

<property name="portletModeMap">
<entry key="view" value-ref="searchController" />

<!-- Define Controller Bean -->

The problem is fixed by adding the following line in *.gwt,xml

<add-linker name="xsiframe" />

but what is this line of code for?
