Re: T5.2: Javascript document.getElementById() after zone update
It is changing indeed. So I guess I will try using getElementsByClassName(
'i-can-constant')[0] instead. Thanks.

Subject: Re: T5.2: Javascript document.getElementById() after zone update
Hi
When you click 'View Source Code' in a browser, it shows you the html loaded
first time the page was loaded and does not show the dom changes done using
ajax. If you want to see the latest dom, install firebug on firefox(chrome
has a very similar one by default) and enable it by clicking on the bug icon
on the status bar.
Also, how are using getting the element id of select in your javascript ?
regards
Taha

Try using a class instead of id?

Hi all,
At the end of a zone block, I call a JS function which tries to get an
element (that is also inside the zone) by calling
document.getElementById('componentSelectId'). The first time the page loads
and the zone is rendered everything works as it should. Although, when I
update the zone, by changing the value of a select component, the JS gets
executed, but document.getElementById('componentSelectId') returns null.
Looking at the page source on the web browser I can see that the element is
there with the very same id. Anybody can tell what is going on here?
Thanks.
Re: Exception starting filter test
Just a guess, but normally the filter is named app instead of app1. The filter name affects the name of the app module class Tapestry looks for.

Re: Invoke method after page is loaded; when method finishes, redirect to another page
Thanks all for the tips!
I must admit I looked into all your suggestions and links, but wasn't able
to get my head around them.
But I managed to come up with the workaround. Since I'm using JQuery
Tapestry module, I was able to display ajax loader icon and appropriate text
on the form submit. This code will actually be invoked before the form
submit.
script
$(#keywordsForm).submit(function () {
$(#loadingText).html('img src=${context:images/ajax-loader.gif} /
Please wait.');
});
/script
Thanks anyway, I appreciate it!
Best,
Nikola

I'm new to Tapestry, and I have a problem with a simple Login form. When in
the OnSubmit callback of the form, the login and pasword fields are empty.
Could someone help me at least understand why?

waitForPage / onDOMLoaded hybrid
Hi all,
i'm using tapestry 5.1.0.5 on this particular project.
I'm not 100% sure this isn't already available, but before duplicating
logic i thought I'd check...
I need to be able to call a function at any point in the page state (ie
before it's loaded, during loading, after load) but have it wait until
tapestry.init has been called.
Kind of how Tapestry.waitForPage works, except that if the page has not
loaded, instead of showing a dialog, it would register it for invoking
once the page is loaded.
so in psuedo:
function(callback)
{
if(Tapestry.pageLoaded)
invoke(callback);
else
Tapestry.onDOMLoaded(callback);
}
2 questions:
a) is this functionality already available? where?
b) would the above approach be fool-proof? ie would there be a case
where Tapestry.pageLoaded == false and Tapestry.onDOMLoaded would still
not invoke the callback?
thanks, p.

Re: waitForPage / onDOMLoaded hybrid
In lieu of a better (tapestry provided) solution, this is what i'm
using. It seems to work, but I can see the need to make the callbacks
parameterised in the future (which currently isn't supported by
Tapestry.onDOMLoaded)
function callWhenPageLoaded(callback)
{
if (typeof(Tapestry) == undefined)
throw(callWhenPageLoaded called too early);
if (Tapestry.pageLoaded)
callback.call(this);
else
Tapestry.onDOMLoaded(callback);
}
If something like this doesn't exist in tapestry already, I think it should.

I don't think we need to replicate functionality provided by javascript
libraries.
Tapestry provides onDOMLoaded and waitForPage .. the functionality I
describe isn't provided by Tapestry or a javascript library (since the
js lib would need to know about the Tapestry js api).
I'm not sure what you mean by that statement Josh, I'm proposing a
useful utility method inseparable from the tapestry js api so that other
users don't have to write and embed the method themselves also.

It doesn't go back to the server. Anything added by
RenderSupport.addScript() (JavaScriptSupport in T5.2.4) is added inside a
JavaScript block inside body:
Tapestry.onDOMLoaded(function() { ... // your JavaScript code added
through addScript() here });
Check the source of any page generated by Tapestry and you'll find this as
the last script element inside the body
