Adding "freeze" keyword. Not sure if that's correct. Please correct any errors.

I accept. This might have been fixed because of the culling of deadlocking
calls made by Webclient. Will try to reproduce with latest builds.

ViewPageSource function is unavailable in webclien GUI now. There is
only "viewPageSource as String" function.
Thats why I cannot reproduce(not-reproduce) this bug.

Vladimir, The
string ViewPageSource()
function is in keeping with the original Webclient API. This method is
implemented purely in Java and so should not cause any hanging of Mozilla. Pls
test this implementation as it stands and let me know if there are any problems
with it. Otherwise I will be closing this bug.
thanks much.

Ashu, due to changes in EMWindow.java from version 1.24 to 1.25 "View Page
Source" menu item was changed with "View Page Source as String". And in
function actionPerformed now currentPage.getSource() invoked. But here is
output of webclient:
The Current URL is -- http://www.mozilla.org/projects/blackwood/webclient/
+++++++++++ Page Source is +++++++++++
null<HTML><HEAD> <META HTTP-EQUIV="Content-Type" CONTENT="text/html;
charset=iso-8859-1"> .....
Why the first word of source is null? Is it correct behaviour?
If in actionPerformed I use next code:
byte source[] = EMWindow.this.currentPage.getSourceBytes();
String sou = new String(source);
System.out.println("+++++++++++ Page Source is +++++++++++\n\n" + sou);
I receive the same output.
Can you comment it?

I cannot compile sources with you patch due to this errors:
org/mozilla/webclient/wrapper_native/CurrentPageImpl.java:170: variable
HTMLContent might not have been initialized
HTMLContent = HTMLContent + line;
^
org/mozilla/webclient/wrapper_native/CurrentPageImpl.java:179: variable
HTMLContent might not have been initialized
return HTMLContent;
^
org/mozilla/webclient/wrapper_native/CurrentPageImpl.java:203: variable
HTMLContent might not have been initialized
HTMLContent = HTMLContent + line;
^
org/mozilla/webclient/wrapper_native/CurrentPageImpl.java:211: variable
HTMLContent might not have been initialized
result = HTMLContent.getBytes();
^
4 errors
I think, HTMLContent variable should be initialized first, in definition.
With my patch both tests passed.
