Re: T5: Clicking on actionLonk with a zone parameter before page loads
Ironic that you are pointed to yahoo for a solution when the advice they
advocated to the community is to load scripts after markup, all for the false
hope of a performance increase, which is ultimately incorrect and is creating
these types of problems... your markup (hence actionlinks etc) should never be
allowed to render until the scripts have loaded and the DOM is available.
See http://www.quirksmode.org/js/placejs.html at the bottom of the page:
Quote: Placing scripts in the head makes sure that any functions are loaded
before the buttons, links or other things that call them are loaded. If you put
your scripts at the very end of a page, it is possible that a user already sees
part of the page including a button with a JavaScript function call, while the
rest of the page hasn't loaded yet. Result: user pushes button and gets
JavaScript Error Message Alerts, because the browser can't find the script
(yet). Unless there's a good reason to do otherwise, place your scripts in the
head
Fortunately this is now configurable in Tapestry.
public static void contributeApplicationDefaults(
MappedConfigurationString, String configuration) {
configuration.add(SymbolConstants.SCRIPTS_AT_TOP, true);
}
And I bet your problem goes away.

Russell,
I you look at YUI's event model I belive it handles this better.
YUI Event - http://developer.yahoo.com/yui/event/ will allow you define
events before DOM Ready and queues them until after.
This should be a good way to solve this problem.

Can you tell me what happens now? Is the link just dead until the page
loads, is there some sort of feed back? Is It invisible? Just want to
know as we were about to roll our own solution.
Many thanks

Last version of T5 has a fix for this. Works for me now.

Hi,
I have some AJAX calls from actionLinks. If a user clicks on the
actionLink before the page is fully loaded I get the exception
A component event handler method returned the value
[EMAIL PROTECTED] Return type
org.apache.tapestry5.internal.structure.BlockImpl can not be handled.
Configured return types are java.lang.Class, java.lang.String,
java.net.URL, org.apache.tapestry5.Link,
org.apache.tapestry5.StreamResponse,
org.apache.tapestry5.runtime.Component.
Is this something to do with javascript setting up the zones on load?
Is there a work around or a planned fix for this? We use ajax calls
all
over the site and everyone can cause this kind of explosion if we have
a
fast clicker.
Cheers

Hi Peter,
Thanks for that. To try it I guess I have to upgrade to 5.0.17 ?
