[jira] Commented: (TAPESTRY-1379) Exception when creating widgets
on AJAX requests
[ https://issues.apache.org/jira/browse/TAPESTRY-1379?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12483479 ]
Andreas Andreou commented on TAPESTRY-1379:
-------------------------------------------
As mentioned in one of your emails "it's sufficient to append to the bottom of core.js the line
dojo.require("tapestry.widget.Widget"); and it magically works"
So, this is probable a duplicate of https://issues.apache.org/jira/browse/TAPESTRY-1219
My workaround was the same as yours, i.e. add dojo.require as the page initially loads
Anyway, adding dojo.require("tapestry.widget.Widget") in core.js may solve this particular case (TAPESTRY-1379),
but it won't really help if an ajax response requires a custom 'class' and the framework uses it before it gets
fully loaded (TAPESTRY-1219)

> Teh problem is this:
> when you have a page with a form that initially doesn't display any widget and, on form ajax submission you want to display a widget, if you use client side validation you'll get this exception on next submit if a client validation exception is fired:
> ERROR: 14:35:46: Error validating Error : Could not locate widget implementation for "alertdialog" in "tapestry.widget" registered to namespace "tapestry" : http://localhost:8080/app?service=asset&path=%2Fdojo%2Fdojo.js : line 756
