BUG: DhText Gets Interpreted as HTML Code

MORE INFORMATION

The DhText element currently creates a <SPAN> tag, followed by your literal text, followed by a closing </SPAN> tag. Your HTML characters are not translated into references, so if DhText contains HTML tags, the characters will be rendered as HTML. For example calling dhText.setText("X + Y < Z. A + B > C."); will generate the following HTML:

<SPAN>X+Y<Z.A+B>C.</SPAN>
				

This will incorrectly result in "X + Y C."

To see if any translation is occurring, you can create a DhText object, obtain the peer class, and inspect the Inner HTML results. The following method demonstrates one possible implementation of checking for translation of the original message:

boolean noTranslation() {

   String content="<B>&>";
   DhText text=new DhText(content);
   text.setVisible(false);
   add(text);
   com.ms.wfc.html.om.IHTMLElement peer;
   peer=(com.ms.wfc.html.om.IHTMLElement)text.getPeer();
   String inner=peer.getInnerHTML();
   remove(text);
   return content.equals(inner);

}
				

Steps to Reproduce Behavior

1. In Visual J++, select New Project from the File menu.
2. In the New Project dialog box, click the New tab.
3. In the Visual J++ Projects tree, click Web Pages.
4. Click Code-Behind HTML.
5. Click Open to create the project.
6. Modify Class1.java as follows:

   import com.ms.wfc.html.*;
   import com.ms.wfc.core.*;
   import com.ms.wfc.ui.*;
   public class Class1 extends DhDocument
   {
      public Class1()
      {
         initForm();
      }
      private void initForm()
      {
      }
      protected void onDocumentLoad(Object sender, Event e)
      {
         DhText text=new DhText();
         String message="<B>BOLD</B><HR><U>UNDERLINE</U>&<TAG&>";
   
   // Workaround: Uncomment the next two lines for one possible
   // workaround.
   //    if (noTranslation())
   //       message=toHTMLViewable(message);
         text.setText(message);
         add(text);
      }
      boolean noTranslation() {
         String content="<B>&<";
         DhText text=new DhText(content);
         text.setVisible(false);
         add(text);
         com.ms.wfc.html.om.IHTMLElement peer;
         peer=(com.ms.wfc.html.om.IHTMLElement)text.getPeer();
         String inner=peer.getInnerHTML();
         remove(text);
         return content.equals(inner);
      }
      static String toHTMLViewable(String text) {
         // indexOf() returns -1 if not found:
         if (text.indexOf('<')+text.indexOf('>')+text.indexOf('&')==-3)
            return text;
         StringBuffer buffer=new StringBuffer(text);
         int index=0;
         String amp="amp;";
         String less="<";
         String greater=">";
         while (buffer.length()>index) {
            if (buffer.charAt(index)=='&') {
               buffer.insert(index+1,amp);
            } else if (buffer.charAt(index)=='<') {
               buffer.setCharAt(index,'&');
               buffer.insert(index+1,less);
            } else if (buffer.charAt(index)=='>') {
               buffer.setCharAt(index,'&');
               buffer.insert(index+1,greater);
            }
            index++;
         }
         return buffer.toString();
      }
   }
   						

7. Modify Page1.html as follows:

   <HTML>
   <BODY>
   <hr>
   <OBJECT classid="java:com.ms.wfc.html.DhModule"
       height=0 width=0 ... VIEWASTEXT>
   <PARAM NAME=__CODECLASS VALUE=Class1>
   <PARAM NAME=CABBASE VALUE=Project1.CAB>
   </OBJECT>
   <!-- Insert HTML here -->
   </BODY>
   </HTML>
   						

8. Run the project.

You will get the following Web page: Expect result is as follows:
