ok, so you also have to pass the action name to preAction() and
postAction().
def preAction(self,actionName):
pass
def postAction(self,actionName):
self.writeHTML()

I assume you are inheriting from WebKit.Page. Look at the preAction()
and postAction() functions there. As those functions are implemented,
when you call an action, the doctype and header ar printed, then your
action is called, then any closing tages (body,html) are printed (this
is from memory, check the code to be sure). So when you call
writeHTML() from an action, some of what is going to be written has
already been written. On this list I read someone say that the default
implememtation of the actions is an anemic version of writeHTML().
My suggestion would be to do the following:
..in your servlet
def preAction(self):
pass
def postAction(self):
self.writeHTML()
and don't write anything out to the screen in your action.

if i call self.writeHTML() from an action, it prepends a redundant
header to the output :
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
"http://www.w3.org/TR/html4/loose.dtd";>
<html>
<head>
<title>ServletNameInsteadOfCheetahTemplateTitle</title>
</head>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<meta content="text/html; charset=ISO-8859-1"
http-equiv="content-type">
<title>Title set in cheetah template</title>
<link rel="stylesheet" href="/common/style.css" type="text/css">
<script language="javascript" type="text/javascript"
src="/common/lib.js"></script>
</head>
however, just accessing the servlet directly without an action does
not prepend the redundant header.
i don't use any methods in the servlet except writeHTML() because i
use cheetah templates to generate the output, which i render with
self.writeln(templateOutput)
i have a feeling i may be using the class incorrectly; nor have i
scoured my code yet - just wondering if anyone sees something
glaringly obvious, or has come across this before.
thanks
