> -----------------------------------------------------------------------------------------------
>
> Key: TAPESTRY-1527
> URL: https://issues.apache.org/jira/browse/TAPESTRY-1527
> Project: Tapestry
> Issue Type: Bug
> Components: XHR/dhtml/Ajax
> Affects Versions: 4.1.2
> Environment: JRE1.5.0.7, Tomcat 5.5, WinXP, Firefox 2, IE 7
> Reporter: Christian Dutaret
> Assignee: Jesse Kuhnert
> Fix For: 4.1.2
>
> Attachments: Dialog.script
>
>
> Issue with the dojo javascript with the @Dialog component and EventListener
> annotations:
> - the @Dialog component is initialized as hidden
> - A user clicks on a link, which triggers an EventListener, which updates a
> component that wraps the @Dialog and makes it visible
> - within the Dialog, a "Close" button is displayed. When the user clicks on
> it, it triggers the EventListener again, the wrapper component is updated and
> the Dialog is set back to hidden.
> Everything works as expected, but once the Dialog has been opened then closed
> once, every scroll event on the page triggers js errors.
> on FF2.0 : "node has no properties" on line 96 in dojo.js
> on IE7 : "offsetWidth is null or is not an object" (freely translated from
> french)
> Tried it on 4.1.1 and latest 4.1.2 snapshot : exact same behavior.
> my HTML template:
> <span jwcid="[EMAIL PROTECTED]">
> <div jwcid="[EMAIL PROTECTED]" hidden="ognl:hidden"
> backgroundColor="blue">
> <div style="background-color: white; border-width: 1px; width: 600px;
> height: 400px;">DIV content<br />
> <form><input type="button"
> onclick="someJsThatEventuallyTriggersTheEventListener();" value="Close"
> /></form>
> </div>
> </div>
> </span>
> my page class:
> @InitialValue("true")
> public abstract void setHidden(boolean value);
> @EventListener(elements = "dialwrapper", events = "someCustomJsEvent",
> submitForm = "hiddenFormWhichUpdatesSelectedAnnounceId")
> public void selectAnnounce(IRequestCycle cycle, BrowserEvent event) {
> setHidden(getSelectedAnnounceId() == null);
> cycle.getResponseBuilder().updateComponent("dialwrapper");
> }
