Binding a snippet in a comet actor?

[Somindra Bhattacharya]

Hi Everyone,

I have a comet actor that binds XHTML. The XHTML corresponds to a
snippet:

XHTML for comet actor ->

<lift:comet type="RCActor">
<Act:act />
</lift:comet>

When the comet actor receives a certain message, the render method of
the comet actor binds the following XHTML ->

<lift:Discuss.invite form="post">
<elem:submit />
</lift:Discuss.invite>

The Discuss snippet's "invite" method definition is:

def invite(xhtml: NodeSeq): NodeSeq =
{

def handleSubmit() =
{
Log.info("GOT A SUBMIT IN INVITE")
}

bind("elem", xhtml,
"submit" -> submit("Click", () => handleSubmit()))
}

The page does not contain this form when it is first loaded. When the
actor receives a certain message, it binds the XHTML (Discuss.invite)
to the page and the form and the "submit" button are rendered
properly.

However, when I click on the submit button, the "handleSubmit" method
is not called. Instead, the browser displays a page with the text
"window.location=/".
If I use the browser back button and re-visit the page with the comet
actor, the submit button works (i.e., handleSubmit() is called and I
can see the info log).

Is this approach "legal"? Is there a way to make a form submit if it
was not originally part of the page?

Thanks,
Som

What about an Ajax form?

[Somindra Bhattacharya]

Thanks for responding, Naftoli.

I tried changing the code to:

def handleSubmit() =
{
Log.info("GOT A SUBMIT IN INVITE")

net.liftweb.http.js.JsCmds.Run("alert('Hey')")
}

ajaxForm(
bind("elem", xhtml,
"submit" -> submit("Click", () => handleSubmit() ),
) ++ hidden(() => handleSubmit())
)

The handleSubmit method is still not called. I tried using ajaxButton
instead of submit but that did not help either.

What am I doing wrong?

Apologies for bumping this.

Is there a way to get the submit button (or an ajaxButton) to work if
the snippet which was not originally part of the page is bound by a
comet actor?

Thanks,
Som

The chat example in demo.liftweb.net (source in examples/example) has a form that is presented after the initial form is rendered.  It works just fine.

Please put together a small example of the failure so I can see the running code.

David,

Thanks for responding.

I have hosted the example at http://174.129.214.150:8080/

The code is at http://174.129.214.150:8080/dynamicForm.tar.gz

Here are the steps to reproduce the issue:

1. Open http://174.129.214.150:8080/ in a browser window. This starts
a comet actor which listens for messages. There is no form present on
this page.

2. Open http://174.129.214.150:8080/testdriver in another browser
window. Juxtapose these two windows.

3. Click on the "Click here" button in the window opened in (2).
Submitting this form results into a <lift:Snippet> block being sent to
the actor on the index page. This makes the index page show a form
that was not previously present.

4. Click on the button that has appeared on the index page. This does
not result into calling the handler at the server end.

Please let me know if you need more information.

Thanks again...

Regards,
Som

I have a similar problem here. I didn't find this issue on github.
Is this issue solved?

Thanks,

Felipe

Yes. 

The issue is here: http://github.com/dpp/liftweb/issues/closed/#issue/93

It was fixed in 1.1M7 and later.

The problem was using Google Chrome to see this page. On firefox it shows up normally.
