Are you adding this to *every* component that you want to track? It's hard
to tell, but the method signature of your checkKeyPress makes me think you
might be.
Although not directly answering your question, I'd actually do it the other
way around:
1 - use an ajax behavior (not a timer) and wrap it in a custom function like
"startKeepAliveTimer()".
1b - in the onRespond of this behavior, simply add a new ajax timer to the
page and let it run continuously
2 - then any component that can accept key presses that should trigger a
keep alive timer can have a normal (non-ajax) behavior attached to them that
appends onkeypress="startKeepAliveTimer()" to their tag. (this could even
be done automagically via component instantiation listener, or IVisitor,
etc)
This is an easy way to have a single AJAX keep-alive timer for all of your
components on the page.

Re: using ajaxlink when deployed to google app engine
Please help me with the issue , I am trying to deploy wicket in google app engine, i was able to bring up the home page ,then for further testing I added a simple ajaxlink , when I click on the link nothing happens then I enabled logging of wicket and saw this in logs FINE: ending request for page [Page class = org.radiosai.saibaba.web.page.HomePage, id = 0, version = 0], request [method = GET, protocol = HTTP/1.1, requestURL = http://localhost:/app/, contentType = null, contentLength = -1, contextPath = , pathInfo = null, requestURI = /app/, servletPath = /app/, pathTranslated = null] Jan 8, 2011 1:04:01 AM com.google.appengine.tools.development.LocalResourceFileServlet doGet WARNING: No file found for: /app/resources/org.apache.wicket.ajax.WicketAjaxReference/wicket-ajax.js Jan 8, 2011 1:04:01 AM com.google.appengine.tools.development.LocalResourceFileServlet doGet WARNING: No file found for: /app/resources/org.apache.wicket.markup.html.WicketEventReference/wicket-event.js Jan 8, 2011 1:04:01 AM com.google.appengine.tools.development.LocalResourceFileServlet doGet WARNING: No file found for: /app/resources/org.apache.wicket.extensions.ajax.markup.html.modal.ModalWindow/res/modal.css Jan 8, 2011 1:04:01 AM com.google.appengine.tools.development.LocalResourceFileServlet doGet WARNING: No file found for: /app/resources/org.apache.wicket.extensions.ajax.markup.html.modal.ModalWindow/res/modal.js please advice me how to resolve this ? -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/using-ajaxlink-when-deployed-to-google-app-engine-tp3178810p3204602.html Sent from the Users forum mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
AbstractAjaxTimerBehavior and getPreconditionScript
I am writing code that checks whether the user has typed something in the
page, and if so, goes an AJAX call to keep the user session alive.
For this I am using AbstractAjaxTimerBehavior to ping the server every
certain time, and overriding its getPreconditionScript() method to call a JS
function that knows if the user has typed something since the last AJAX
call.
This works well as long as the user types something between the time calls,
but if ever the getPreconditionScript() determines the user has not typed
anything, then the timer will stop.
I would expect the AJAX call not to be made, but the timer to continue to
run for the next time, so if the user types something, then the call will be
done in the next run.
What is the correct behavior in this case? Do I have a bug, or is it working
as written? If the second, then any ideas how to avoid the timer from
stopping?
Code is below. Thanks for your help.

Re: IndicatingAjaxButton (Doesn't display indicator in Internet Explorer)

Re: Show wait cursor on every action
Either I don't understand you again or you don't know how page load works. When you click a link (no ajax involved) then a request is sent to the server and the server returns a response which kinda overrides the previous response. I.e. when you click the link you change the cursor to be pointer but then the this page is unloaded and completely new one is loaded in the browser. The new one doesn't know anything about the state of the previous one, i.e. the cursor is 'default' initially. You can keep the state in http parameter or cookie but you can have the chance to set the old state to the new page as soon as 'ondomready' but at that time you want to reset the cursor to 'default' so there is no point to keep this state at all.

Re: Show wait cursor on every action
Thanks Martin, and excuse me. But i didn't describe the whole problem. I want to click a link and load another page (simply by calling setResponsePage). I already tried a solution like But it seems that onload is called if html code is loaded (as name says :-). But i would like to "reset" the cursor if page is rendered. Otherwise i always have a gap between "end of wait cursor" and "page content is presented". I also tried AbstractBehavior with "ondomready" and "onload". But i had no luck :-(. If i could get an event if page is rendered then all would be fine. You know a way to get that?

RenderBodyOnly and email links
Many may already have realized this, but for anyone who hasn't, I just came
across this elegant way to handle optional emails.
The user/admin stuff is just an example use-case, simplified to fit here.
// User's Statement page lists some items and who bought them...
AbstractLink myLink;
if (isAdminUser()) {
// admins can view the buyer's full info
myLink = new BookmarkablePageLink("buyer.link",
MemberPage.class, params)
} else {
// normal users get email links to each other instead
myLink = new ExternalLink("buyer.link", email);
// or if they don't have email, just show their name
myLink.setRenderBodyOnly(email.isBlank());// if they don't have
an email
}
myLink.add(new Label("buyer.name"));
Before I found this, I had two separate elements - the a link with it's span
name inside, and then another span name with only one or the other visible -
that was ugly.
Maybe this helps someone else
Cheers,
Jim

Print all HTML content to file
I have used the WicketTester to print out the rendered HTML content from wicket. I did that through the unit tests. How would I run a similar operation to return the rendered output document outside of WicketTester.I want to print the document from within my J2EE server. Here is the example junit code. private WicketTester tester; // start and render the test page tester.startPanel( TestRenderPanel.class ); tester.getServletResponse().getDocument(); ...
