[T5.1] PageDocumentGenerator Broken?
Hello all,
My ultimate goal is to have a portion of a page render into a string so I
can email this rendered HTML. In trying to do this, I decided the best
(only?) approach is to use the PageDocumentGenerator in the onSuccess method
of the page form (the form is used to capture the email address, etc.).
Something like this:
Object onSuccessFromMyForm()
{
Document doc = pageDocumentGenerator.render("MyPage");
Element element = doc.getElementById("itemblock");
StringWriter buffer = new StringWriter();
PrintWriter writer = new PrintWriter(buffer, true /*autoflush*/);
element.toMarkup(writer);
String items = buffer.toString();
//Do something with the rendered info...
return null;
}
My page template is about as simple as can be:
<html xmlns:t="http://tapestry.apache.org/schema/tapestry_5_1_0.xsd"
xmlns:p="tapestry:parameter">
<form t:id="myform">
<input type="submit" value="Do It" t:type="submit"/>
</form>
<div id="itemblock">
Hello World!
</div>
</html>
But when I submit the form, I get an application exception "Form components
may not be placed inside other Form components." (more below)
Has anyone been able to get this to work, or have a better way to approach
this?
Many thanks,
Levi

Re: [T5.1] PageDocumentGenerator Broken?
Posted by xfile80303 <le...@grokers.net>.
Thanks Josh.
Unfortunately I can't do that since there is session state involved in the
rendering.
I've tried a slightly different approach (abandoning PageDocumentGenerator
as broken) thinking perhaps since this works for AJAX requests maybe I could
render a block in this way, and I've met with some limited success.
I'm able to get simple text rendered, but the mere addition of a simple loop
component blows it up. I'm quite frustrated with this at the moment.
Perhaps some other eyes?
Here's what I've got... if you replace the content of the "emailblock"
component with just "Hello World" you'll get the Hello World text wrapped in
an ajax-partial tag. Which is nearly usable:
<ajax-partial> Hello World! </ajax-partial> However, with a loop it gives a
NPE down in the internals (see below).

Re: [T5.1] PageDocumentGenerator Broken?
Posted by Josh Canfield <jo...@thedailytube.com>.
I went down a similar path on thedailytube.com for sending email
forwards. The challenge you are seeing here is with the Environment.
The form is checking in setupRender for an existing FormSupport object
and complaining because it already exists. The environment that you
are trying to render with is the same one you are using to process the
form. There are a couple of objects that you will run into problems
with (can't remember off the top of my head, and I did it with a much
older version). You can try popping/pushing the objects out of the
environment while you are running your rendering, but this solution is
messy and brittle.
I eventually gave up and just created a separate page with the content
and do an HTTP request to grab the rendered content...
Good Luck!

Re: [T5.1] PageDocumentGenerator Broken?
Posted by xfile80303 <le...@grokers.net>.
Hi Thiago,
Yes, I'm sorry, you are correct. In my attempt to get a small "working"
example, I stripped out the head tag.
Here's my corrected template:
<html
xmlns:t="http://tapestry.apache.org/schema/tapestry_5_1_0.xsd"
xmlns:p="tapestry:parameter">
<head>
<title>My Page</title>
</head>
<body>
<form t:id="myform">
<input value="Do It" t:type="submit"/>
</form>
<div id="itemblock">
Hello World!
</div>
</body>
</html>
But unfortunately I still get the same error.
org.apache.tapestry5.runtime.ComponentEventException
Render queue error in SetupRender[MyPage:myform]: Form components may not be
placed inside other Form components.

7 <body>

The part I don't understand is that the page initially renders without
complaint... it is only when it is trying to render the page for the
PageDocumentGenerator that it has these mysterious issues, which makes me
think something's not working correctly with the PageDocumentGenerator
service.
Cheers,
Levi

It may be not related to your problem, but shouldn't your template have a
head tag?
