wicket abort ajax handling of multipart form when the server is stopped
in normal case, I have tested that wicket ajax multipart form submit event can be triggered properly in this sequence onbefore onprecondition onbeforesend onafter onsucess oncomplete but when the server is stopped and the same ajax multipart form is submitted, only these events are triggered onbefore onprecondition onbeforesend onafter i.e. the onfaliure, oncomplete are not called and the browser is just hanged and the wicket js is waiting forever for load.handleMultipartComplete from the upload iframe, i.e. this ajax form submit is not completed and further ajax event will be just queued from the firebug console, the iframe html can be found as: the html inside the iframe simply means Connection Error so how can I proceed to handle this problem? -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/wicket-abort-ajax-handling-of-multipart-form-when-the-server-is-stopped-tp4670076.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

request time logging with application and network time disguished
we are trying to do logging on the request time to check the application processing time and the request output network time we first try to time the request processing by overriding WebRequestCycle#onBeginRequest, #onEndRequest but it seems the processing time is the same as the request time logged at tomcat, i.e. it includes both application+request output network time can i log the application time, isolating the request output network time? i check that i am using IRequestCycleSettings.RenderStrategy REDIRECT_TO_BUFFER, by which the IRequestCycleSettings.RenderStrategy class javadoc says: * bufferResponse (defaults to true) - True if the application should buffer responses. This * does require some additional memory, but helps keep exception displays accurate because the whole * rendering process completes before the page is sent to the user, thus avoiding the possibility of * a partially rendered page. so we can time the whole wicket rendering process (the application logic) before sending out to the client? can anyone point out where i can add the timing by myself? if wicket does not have an easy extension point here, i can just go to the code and compile for my use myself many thanks -- View this message in context: http://www.nabble.com/request-time-logging-with-application-and-network-time-disguished-tp22530747p22530747.html Sent from the Wicket - User 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

Re: Turn off form validation
i also have a similar use case that requires turning off validation for
some ajax button links
e.g.
i have a form, that may have some text fields with different/none validators
and i want to do translation on some of the text fields by
ajax/dynamically,
so i need to use ajax button links to submit the form with the latest
input values to backend logic
for this case, we want to supress the validation error (if any) and have
wicket to still propagate the form fields to our model automatically
we can't use setdefaultformprocess to false for the ajax button link
so i go to have a look at the form processing, and copy the wicket's form
property propagation logic to my form's onerror:
code
@Override
protected void onError() {
// just for demonstration, can make it happen only for certain cases only
// before updating, call the interception method for clients
beforeUpdateFormComponentModels();
// Update model using form data
updateFormComponentModels();
// Persist FormComponents if requested
// private, can't call
// persistFormComponentData();
super.onError();
}
/code
there may be problem in propagating the form fields to model if there is
validation error,
but it looks ok to me because the form fields with no validation error
should still get their values submitted and propagated nicely, event some
other form fields may have validation error

I solved similar problem where I had some required TextField components
and an AJAX component which does a AJAX submit. During this AJAX submit I
wanted to prohibit all the form validations. I achieved this by setting
the AJAX components (an autocomplete TextField with custom AJAX behaviour)
into its own nested form... form which is inside another form.
I'm not sure does this solve your problem. I found my solution just by
trying differend solutions and it worked :)
hbf wrote:
I have a custom component that allows the user to select one or more
tags. For this, the component has a text field and an AjaxButton Add
to add a tag.
All works fine if I use the component in a form without validation
errors. If, however, a text field has setRequired(true), the
AjaxButton's onSubmit() method is not called (but onError() instead).
In this case, I do not want this behaviour but want form validation
to be disabled for the Add AjaxButton. (I still need to get the
model values updated, though.)
Is there an easy way to achieve this?
I've read about conditional validation,
http://cwiki.apache.org/WICKET/conditional-validation.html
but as my component does not know about the enclosing form, I am
looking for another solution.
Many thanks,

To give a short summary: I investigated one of my apps with YSlow and started optimizing it's interface rendering speed [1]. Especially Wicket's way of handling resources, i.e. JS and CSS files, causes interfaces to load rather slowly. In my articles, I explain how to modify the cache interval [2], how to mount resources with a version (e.g. /css/all-1234.css) in order to use aggressive client-side caching (e.g. resources expire after a year) [3]. Finally, I show how to merge resources at application startup (using a class classed MergedResourceStream) to reduce the number of resources a client has to download [4], including code). I was able to increase interface loading times considerably, so it's surely worth a look. I feel that it would also be worth to discuss, whether this work could be part of upcoming Wicket versions.

Re: client side handling of ajax request session expiration
the implementation of js failure handler does not work for the case
(from tracing the js codes)
i guess it is because the ajax session expire exception thrown to the
client contains redirect path information, by which wicket just use this
redirect path and ignore the failure handler
and i have come up a quick solution:
override the method WebRequestCycleProcessor (i.e. need to register your
custom processor)
code
public IRequestTarget resolve(RequestCycle requestCycle,
RequestParameters requestParameters) {
try {
return super.resolve(requestCycle, requestParameters);
} catch (RuntimeException re) {
if (re instanceof PageExpiredException) {
if (((WebRequestCycle)
requestCycle).getWebRequest().isAjax()) {
// return a custom ajax request that only contains
failure handle js
/*
AjaxRequestTarget art = new AjaxRequestTarget(null);
art.appendJavascript(your failure handler js);
return art;
*/
}
}
throw re;
}
}
/code

Hi-
not sure if this helps in your case, but if you define the
wicketGlobalFailureHandler() JavaScript function, it will be called
if your ajax request fails (because of page expiration or any other

Or use Wicket.Ajax.registerFailureHandler(function() { ...}) (but I
never tried that myself).

i have configured the tomcat (6.0.13) to use SSL when i access my app under https and try to check the HttpServletRequest.isSecure (the http servlet request is retrieved from RequestCycle.get()), it always returns false (i have already configured the tomcat connector to returns true for the secure attribute) i don't know if it relates to wicket, but want to see if i can get any hint for this problem if somebody here is successful in using wicket+tomcat for this case -- View this message in context: http://www.nabble.com/fail-to-check-HttpServletRequest.isSecure-under-tomcat-tp16603545p16603545.html Sent from the Wicket - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
ajax error handling on server side exception
i can sucecssfuly use getFailureScript to act against the client-side ajax error, i.e the server is down and ajax request is sent with failure can we have similar facility for server-side exception upon ajax request? e.g. for now, if the server throw exception during onevent of an ajax request, the response will trigger a redirect to error page, we want to re-use something similar to getFailureScript to handle the error at client side a suggestion that may work is to try-and-catch all exception happened during onevent of ajax request, and send back a error-javascript to the ajaxTarget(.appendJavascript); but we think that this is difficult and troublesome to refactor all of our ajax code, and -- View this message in context: http://www.nabble.com/ajax-error-handling-on-server-side-exception-tp16624390p16624390.html Sent from the Wicket - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: pass information through ajax without form
i have traced the wicket source codes at the place that how it generates the
ajax js like
wcall=wicketAjaxGet('xxx')
but i don't know exactly what this does, so how to add parameter to the
wicket ajax request?
i can add custom js to the wicket ajax javascript, but how can I pass the
some dynamic js state into that ajax request, e.g. i trigger the ajax
request by a link with AjaxEventBehavior on onclick event.
would you mind show me a simple example?

And you need to override (server or client side) the callbackUrl to add
parameter.

it is no problem to use form, but we have a restriction that no form is

Re: pass information through ajax without form
my case is:
there is a javascript variable (let say var STATE;) that will be updated
througout the client side javascript event
there is a link (for example) that I want to use to pass the STATE through
ajax to server.
in your codes, does client side javascript method
DnDSortableBehavior.asQueryString() generate the query string and append
to the wicketAjaxGet? and you parse the parameters in the server side?
I think you have already given me good hints and I will continue work on
that, thanks very much

Currently I have no simple example :-(
In my case (wicketstuff-jquery), I've got a link that call a javascript
function generated (with a template on server side).
In this function :
var wcall = wicketAjaxGet('${callbackUrl}' +
DnDSortableBehavior.asQueryString(), function(){}, function(){});
And the method DnDSortableBehavior.asQueryString() is in charge of
formated collected state, params,...
var DnDSortableBehavior = {
...
asQueryString : function() {
return 'itemId=' + this.itemId + 'srcContainerId=' +
this.srcContainerId + 'srcPosition=' + this.srcPosition +
'destContainerId='+ this.destContainerId + 'destPosition=' +
this.destPosition;
}
};
In my case I use jquery to retrieve states, values.
If I've got time this evening, I'll try to create a sample.
Which type of information do you want to send back to server ?
