adding <script> within generated .html [FIXED]

Postby peterblazejewicz » Wed Nov 07, 2007 2:38 pm

hi,

adding <script> tag (even empty one) within head or body of source .html page generates NullPointerException in Design view,

steps to recreate:

#1
create default project using new GWT project wizard with default module generated

#2
generated source files:

.html
Code: Select all
<html>
   <head>
   
      <!--                                           -->
      <!-- Any title is fine                         -->
      <!--                                           -->
      <title>Wrapper HTML for TestScriptTag</title>

      <!--                                           -->
      <!-- The module reference below is the link    -->
      <!-- between html and your Web Toolkit module  -->      
      <!--                                           -->
      <meta name='gwt:module' content='com.mycompany.project.TestScriptTag'/>

      <!--                                           -->
      <!-- Link CSS file                             -->
      <!--                                           -->
      <link type="text/css" rel='stylesheet' href='TestScriptTag.css'/>   
   </head>

   <!--                                           -->
   <!-- The body can have arbitrary html, or      -->
   <!-- we leave the body empty because we want   -->
   <!-- to create a completely dynamic ui         -->
   <!--                                           -->
   <body>

      <!--                                            -->
      <!-- This script is required bootstrap stuff.   -->
      <!-- You can put it in the HEAD, but startup    -->
      <!-- is slightly faster if you include it here. -->
      <!--                                            -->
      <script language="javascript" src="com.mycompany.project.TestScriptTag.nocache.js"></script>

      <!-- OPTIONAL: include this if you want history support -->
      <iframe id="__gwt_historyFrame" style="width:0;height:0;border:0"></iframe>

   </body>
</html>


generated entry point:
Code: Select all
package com.mycompany.project.client;

import com.google.gwt.core.client.EntryPoint;
import com.google.gwt.user.client.Window;
import com.google.gwt.user.client.ui.Button;
import com.google.gwt.user.client.ui.ClickListener;
import com.google.gwt.user.client.ui.RootPanel;
import com.google.gwt.user.client.ui.Widget;

/**
* Entry point classes define <code>onModuleLoad()</code>.
*/
public class TestScriptTag implements EntryPoint {
   private Button clickMeButton;
   public void onModuleLoad() {
      RootPanel rootPanel = RootPanel.get();

      clickMeButton = new Button();
      rootPanel.add(clickMeButton);
      clickMeButton.setText("Click me!");
      clickMeButton.addClickListener(new ClickListener() {
         public void onClick(Widget sender) {
            Window.alert("Hello, GWT World!");
         }
      });
   }
}


#3
now try to add "script" tag within head or body:
Code: Select all
   <head>
   
      <!--                                           -->
      <!-- Any title is fine                         -->
      <!--                                           -->
      <title>Wrapper HTML for TestScriptTag</title>

      <!--                                           -->
      <!-- The module reference below is the link    -->
      <!-- between html and your Web Toolkit module  -->      
      <!--                                           -->
      <meta name='gwt:module' content='com.mycompany.project.TestScriptTag'/>

      <!--                                           -->
      <!-- Link CSS file                             -->
      <!--                                           -->
      <link type="text/css" rel='stylesheet' href='TestScriptTag.css'/>
      <!-- custom script -->
      <script type="text/javascript"></script>      
   </head>


#4
switch to design view and click refresh

hi guys,

workaround: put everything into external .js (javascript) file and use "src" attribute,

Code: Select all
<script type="javascript" src="config.js"></script>


however I want to use inlined script without using external source,
it is required for simulating server side code injection into hosting page,

regards,
Peter

Give this another try with the latest build.

We now add the content between <script> and </script> as-is, so we should now support both external and inline scripts.
