T4.1.4-SNAPSHOT issue migrating from 4.0.2 with PopupLinkSubmit
We have a link on a page that does a submit and pops up a new window once the
form has been submitted.
The code is based on the PopupLinkSubmit example here:
http://wiki.apache.org/tapestry/PopupLinkSubmit
This all works fine on 4.0.2 but under 4.1.4-SNAPSHOT we get the following
error when the page opens up:

Here's what's on the page:
<a href="#"
jwcid="@PopupLinkSubmit"
listener="listener:openEditorGraph"
popuppage="Waiting"
styleClass="action"
windowWidth="840"
windowHeight="550">
Generate Plot
</a>
Here's PopupLinkSubmit.script
<?xml version="1.0"?>
<!DOCTYPE script PUBLIC
"-//Apache Software Foundation//Tapestry Script Specification 3.0//EN"
"http://jakarta.apache.org/tapestry/dtd/Script_3_0.dtd">
<script>
<input-symbol key="name" class="java.lang.String" required="yes"/>
<input-symbol key="popupLink" class="java.lang.String" required="yes"/>
<input-symbol key="form" class="org.apache.tapestry.IForm" required="yes"/>
<input-symbol key="class" class="java.lang.String" required="no"/>
<let key="href">
javascript:submitPopupLink('${form.name}', '${name}','${popupLink}');
</let>
<let key="class">
${class}
</let>
</script>
Which comes out as:
<a href="javascript:submitPopupLink('editorForm',
'PopupLinkSubmit','/GQ/Waiting.page');" class="action">
Generate Plot
</a>
The Javascript we're rendering in PopupLinkSubmit.java comes out as:
function submitPopupLink(form, elementId, url)
{
var windowName = 'RDQGraphPopup';
var randomNumber = Math.floor(Math.random()*1000);
windowName = windowName+randomNumber;
aWindow = window.open(url, windowName, 'width=840, height=800,
scrollbars=yes,resizable=yes', false);
aWindow.focus();
var form = document.getElementById(form);
form.target=windowName;
form.events.submit(elementId);
form.target='';
}
I can supply the rest of the source if required but it's basically following
the example I mentioned at the top.
The rendered versions of the link and the Javascript are the same as under
4.0.2 but we get the above error in the back end and the link does not work.
We get a Javascript error stating that 'events' is null or not an object.
This is referring to this line:
form.events.submit(elementId);
Which seems to be related to issues mentioned here
http://tapestry.apache.org/tapestry4.1/usersguide/upgrade4.0.html
Can anyone let me know what we should be doing instead of form.events.submit?
The documentation does not make it clear what the replacement is
If we fix the form.events issues will that also fix the error we see when the
page loads up or is that an unrelated error?
Any ideas would be appreciated.

FYI, if we remove the PopupLinkSubmit component we don't get the errors
appearing in the logs so it's definitely related to something in that
component

No ideas are coming to mind right away, other than it looks like it's
trying to do Map related functions without casting to map first. It
is not a critical bug but it could potentially cause problems for you.
Or at least be annoying to see during development and not as fast as
it could be in production.
I'll play around with this popuplinksubmit component later (maybe add
it to contrib) and see what I can find.

OK we updated the generated Javascript with the new version of the Javascript
function
function submitPopupLink(form, elementId, url)
{
var windowName = 'RDQGraphPopup';
var randomNumber = Math.floor(Math.random()*1000);
windowName = windowName+randomNumber;
aWindow = window.open(url, windowName, 'width=840, height=550,
scrollbars=yes,resizable=yes', false);
aWindow.focus();
var form = document.getElementById(form);
form.target=windowName;
tapestry.form.submit(form, elementId);
form.target='';
}
this seems to allow the popup link to work but we're still getting the errors
in the back end.
They don't seem to have any ill effect but they are generated each time the
page serves.
For script generation we are using the version of the call passing this:
getScript().execute(this, cycle, pageRenderSupport, symbols);
(If this is the call Jessie meant)
Any ideas as to what is causing the error? Even though it does not seem to be
causing any problems I've a feeling it's gonna bite us in the ass at some
point...
Here's PopupLinkSubmit.java if it's any help. As I mentioned before it's
mostly copied from the online example I cited before.

I think you need to pass in "this" to your script execute call, the
current method you are executing is deprecated.
For the javascript calls you can refer to
http://tapestry.apache.org/tapestry4.1/javascript/index.html
and
http://tapestry.apache.org/tapestry4.1/jsdoc/index.html
where you should find the new function tapestry.form.submit(form)
(with some other additional documented optional arguments )

> We get a Javascript error stating that 'events' is null or not an object.
> This is referring to this line:
> form.events.submit(elementId);
> Which seems to be related to issues mentioned here
> http://tapestry.apache.org/tapestry4.1/usersguide/upgrade4.0.html
> Can anyone let me know what we should be doing instead of form.events.submit?
> The documentation does not make it clear what the replacement is
>
> If we fix the form.events issues will that also fix the error we see when the
> page loads up or is that an unrelated error?
>
> Any ideas would be appreciated.
